APPENDIX F

FIRE PLANNING PROCEDURES



This appendix implements STANAG 2031 and QSTAG 515.

For the fires of the FA cannon battalion to be effectively massed and employed in support of maneuver operations, those fires must be carefully planned and the fires of the various firing elements must be scheduled. This process of planning and scheduling fires can take place in any of several locations, such as the div arty CP or the division or brigade FSEs. The lowest level headquarters at which fire planning occurs is the cannon battalion assigned the tactical mission of direct support.
In most instances, the maneuver commander determines what he wishes his field artillery to accomplish and the FSCOORD and his staff at the artillery battalion determine the specifics of how to achieve the results the commander desires. The FSEs, on the basis of the maneuver commander's intent for fire support nominate targets to be fired as groups or series or direct the timing, location, and desired effects of a preparation. The cannon battalion S3 then selects and schedules the units to fire. This process in turn drives the positioning and other tactical operations of the battalion.
The fundamentals of fire planning are identical in both TACFIRE and non-TACFIRE battalions. However, the specific techniques involved in automated fins planning differ considerably from those used in manual fire planning. Section I of this appendix presents manual techniques, while Section II discusses automated fire planning procedures.

Section I

MANUAL FIRE PLANNING



Many cannon battalions, particularly those in the Reserve Components, do not have and are not scheduled to receive TACFIRE. Units that are equipped with TACFIRE may lose automated fire planning capability in the battalion FDC because of combat loss or maintenance problems. All artillery battalion O&I elements and FDCs, as well as the FSEs they support, must be capable of planning fires to meet the commander's intent for fire support without the aid of automation. This section outlines the procedures necessary for manual fire planning.

PLANNED FIRES

Fire planning, like fire support planning, is a continuous process conducted by FSCOORDs at all levels to ensure that fires support the maneuver commander's operation plan. As part of the fire planning process, the FSCOORD nominates targets that support a phase of the commander's plan. On these targets, fire is prearranged to ensure responsive engagement when requested. Although some of the planned fires apply to offensive or defensive actions only, others are appropriate to all types of operations and levels of combat. When operating as a part of a multinational force, the US will implement STANAG 2031 and QSTAG 515. The provisions of these ratified agreements have been incorporated throughout the discussions of target lists, target overlays, artillery fire plans, and artillery quick-fire plans in this appendix and elsewhere in this publication.

Procedures for fire planning vary depending on whether the supporting unit is equipped with automated equipment. The manual fire planning techniques for final protective fires, fires using smoke, and schedules of fires are described in the following paragraphs.

Final Protective Fires

Final protective fires are immediately available fires designed to create a barrier to impede enemy movements across defensive lines or areas. They are integrated with the commander's defensive plans and are intended for use primarily against dismounted infantry. Maneuver brigade commanders allocate FPFs to maneuver battalions, which in turn allocate them to their companies. The FPFs are allocated one per firing unit (field artillery), one per section (81-mm mortars), or one per platoon (107-mm mortars). When they are not engaged in another fire mission, weapons are laid on firing data for FPFs. This ensures immediate responses to calls for final protective fires. The shape and pattern of these fires may be varied to suit the tactical situation on the basis of the supported company commander's desires. Authority to call for the FPFs is vested in the supported company commander or platoon leader in whose area they are located. On the target list work sheet, a target is designated as the (or an) FPF target by placing the letters "FPF" in the REMARKS column space for that particular target. The FPF targets are designated by target number.

Fires Using Smoke

Smoke is used to obscure the enemy's view and to screen friendly operations.

Obscuration Fires. Obscuration fires use smoke (HC) and WP shells to suppress the enemy by obscuring his view of the battlefield HE ammunition may have an obscuration effect due to secondary explosions, dust, and fires. This effect should not be relied on. Since smoke is susceptible to changes in wind conditions and the configuration of the terrain, its use must be coordinated with the maneuver commander and all other friendly units that may be affected. Used properly, obscuration fires can do the following:

  • Slow enemy vehicles to blackout speeds.
  • Obscure the vision of direct fire gunners.

  • Reduce the accuracy of enemy observed fires by obscuring OPs and/or COPs.

  • Cause confusion and apprehension among enemy soldiers.

  • Limit the effectiveness of the enemy's visual command and control signals.

Screening Fires. These fires also involve the use of smoke and WP munitions. They are used to mask friendly maneuver elements and to conceal the nature of their operations. For example, they are used to screen river crossings or an enveloping force. Moreover, screening fire may be used as follows:

  • To help isolate an objective by placing smoke in areas beyond the objective.
  • To make the enemy believe that a unit is maneuvering when in fact it is not.

Generally, screening fires require the same precautions as obscuration frees. Smoke screens, however, must be large enough that random enemy firing into them does not produce excessive casualties. Moreover, the establishment of a pattern in the use of smoke and maneuver (such as habitually firing smoke 2 km in front of troops) should be avoided.

Schedules of Fires

Preparation. Preparation fire is fire delivered on targets preparatory to an assault. The preparation is planned by a DS field artillery battalion or higher echelon. It is an intense volume of fire delivered in accordance with a time schedule. The fires normally commence before H-hour and may extend beyond it. They may start at a prescribed time or may be held on call. The duration of the preparation is influenced by factors such as the fire support needs of the entire force, the number of targets and firing assets, and the available ammunition.

The preparation may include a single fire support means (FA only) or multiple means (FA, mortars, CAS, NGF). There is no absolute requirement that the targets in a preparation be phased by target type. Light units may find that they lack the ammunition and the range to fire a phased prep; and heavy units may not have the firing assets, time, or targeting information to do so. However, the process of phasing targets is of substantial value, in terms of both improving the quality of the targeting and maximizing the positive impact of the prep on friendly maneuver operations.



A preparation may be phased to allow successive attacks of certain types of targets:

  • Phase I should provide for the early attack of enemy fire support means and observation capabilities, including FA headquarters and command posts. Such an attack degrades the enemy's ability to react with long-range indirect fires and to gain intelligence about the operation.
  • In Phase II, other CPs, communications facilities, assembly areas, and reserves should be attacked. The goal is degradation of the enemy's ability to reinforce his defense and shift forces to counter our main effort.

  • The final phase should include defensive areas in the forward portions of the enemy position areas and targets that pose an immediate threat to attacking troops. The purpose of this phase is to suppress enemy direct fire systems until our maneuver forces have closed with them.

Provisions must be made to keep hostile fire support means and other critical targets neutralized throughout the preparation, time and ammunition permitting.

When assigning fire support systems to targets in the preparation planners should if possible, ensure that some firing units remain available to attack targets of opportunity. During the firing of a preparation a target of opportunity may pose such a threat to the supported force that some fire support units may have to leave the preparation to attack it. If field artillery is directed to do so, the S3 assigns the units to fire on the target of opportunity.

If fire support units are diverted from the preparation, they rejoin the preparation at the current point in time--not at the time they left it. For example, if a unit firing a preparation is diverted to a target of opportunity at H -5 and takes 4 minutes to attack that target, the unit would reenter the preparation at H -1. This means that some targets may not be attacked at all or may be attacked by fire support assets not originally planned for the preparation. The firing unit diverted from the preparation must report to the appropriate FSE those targets that were not fired or were not fired with the scheduled amount of ammunition. This information lets the FSCOORD and the supported maneuver commander make sound decisions for the attack of those targets while ensuring the safety of the attacking force.

Preparation schedules are continually updated to purge old targets and add new ones. The agency preparing the schedule must set a time after which no other changes can be made. This cutoff time varies among units and is based on training, communication, and scheduling capabilities. The schedule planner must ensure that there is enough time for changes to be sent to firing units, for technical fire direction to be performed, and for ammunition to be prepared and fired. The maneuver force commander, with the advice of his FSCOORD, makes the final decision as to whether a preparation should be fired. This decision is based on such considerations as the following:

  • Will the loss of surprise from the preparation be offset by the damage done to the enemy?
  • Are there enough targets and means to warrant a preparation?

  • Can the enemy recover before the preparation fires can be exploited?

The preparation should begin and end with all firing units that are used in the preparation. Gaps in scheduling (that is, two or more consecutive shift times) should be avoided if possible. Shift time is the interval between the time a cannon unit can have rounds impacting on one target and the time it can have rounds impacting on a new target. Shift time is affected by many variables (such as state of training amount of shift, and type of munition to be fired). For planning and scheduling purpose a shift time of 1 minute is established for light and medium (105-mm and 155-mm) artillery and a shift time of 2 minutes is used for heavy (203-mm) artillery. Any gaps that do occur can be filled by refiring Phase I targets or targets the maneuver commander has designated as priority targets. Units participating in the preparation should not begin firing on targets in a subsequent phase until all units have begun firing on the last target of the current phase or have completed firing the current phase. This may not always be possible, because some weapons may not have adequate range to fire at targets in all phases. In that case, the weapons are scheduled into the phase that is within their capabilities rather than being excluded altogether from the preparation. Fires are planned on the basis of the sustained rate of fire for each weapon system.



Counterpreparation. Counterpreparation fire is intensive prearranged fire delivered when the threat of an enemy attack is discovered. Usually, a counterpreparation is planned by a direct support FA battalion or higher echelon each time the supported force makes an extended halt. These intensive fires are delivered just before the start of an enemy attack. They are designed to--

  • Breakup the enemy's attack formations.
  • Disorganize his command, control and communications.

  • Impair his target acquisition efforts.

  • Decrease the effectiveness of his fire and maneuver.

  • Destroy his personnel and equipment.

  • Reduce his offensive spirit.

The maneuver commander, on advice from his FSCORD, decides when to fire the counterpreparation. Premature firing should be avoided to prevent disclosing targets for enemy counterfires. Counterpreparations are scheduled as on call, since the firing normally depends on enemy initiative.

Like preparation, counterpreps do not have to be phased if availability of time, intelligence, or assets precludes phasing. However, also like preparation phasing should improve the quality of the counterprep and should be done when possible.

Counterpreparations may be planned in two phases. Initial fires (Phase I) should provide for early and simultaneous attack of enemy forward elements, indirect fire systems, and observation posts. In Phase II, the enemy command posts communications, and reserves should be attacked while neutralization of his indirect fire systems continues. Fires from participating units should begin and end together when possible, and gaps should be avoided. When targets are scheduled in a counterpreparation, it is important that firing begin on the last targets of one phase at the same time or before firing begins on the first targets of the succeeding phase. Shift times and sustained rates of fire discussed above for a preparation also apply for the counterpreparation.



Groups, Programs, and Series. Several fire planning techniques are useful when fire is desired on multiple targets. Groups, programs, or series of targets can be established in these situations. The manner in which each of these is graphically shown, the level at which it is established, and its purpose are discussed below.

Groups. A group of targets consists of two or more targets on which simultaneous fires are desired. For FA fires, the DS battalion FDC is the lowest echelon that can plan and implement a group of targets. The FSO determining the need for a group of targets requests the group be planned by the DS battalion FDC. The planning of groups of targets can be a time-consuming process, and the groups can require considerable firing assets. If the FDC does not have the assets available to fire the groups it may pass the request to the force artillery TOC for planning.

A group of targets is graphically shown by circling the targets and identifying the group with a group designator. The designator consists of the two letters assigned to the block of target numbers allocated to a unit (for example, maneuver brigade or div arty TOC) with a number inserted between the two letters. For example, if a brigade is assigned the letters AB, its first group of targets is designated A1B, the second is A2B, and so on.



The fact that targets are included in a group does not preclude the attack of individual targets within the group.

A group of targets is listed on the scheduling work sheet. Groups of targets normally are fired on call of the supported unit. Groups are scheduled so that initial fires strike the targets simultaneously. On the top line of the scheduling work sheet, enter the group number. Below the group number, list the targets of the group opposite the firing unit assigned the targets. Below each target number how the number of rounds to be fired. No line or dot is drawn between the target number and the ammunition. More than one group for a given operation may be scheduled on the same scheduling work sheet.



A firing unit can be scheduled for only one target in each group, and more than one firing unit can be scheduled against a single target if needed.

Programs. A program of targets is a number of planned targets of a similar nature. All targets in a particular program are of the same type (for example all AD targets all OPs, or all mortar targets). A program may be initiated on call at a specific time, or when a particular event occurs.

Each type of program is scheduled starting at 0 and extending as long as needed. Once a program is begun, targets within the program are fired in a predetermined sequence as shown in the schedule. Normally, the lowest echelon that designates and plans programs of targets is the DS field artillery battalion. There are no special graphics associated with a program of targets. Programs appear on scheduling work sheets and schedules of fires.



Series. A series of targets consists of a number of targets and/or groups of targets planned to be fired in a specific sequence to support a maneuver phase. The DS battalion FDC is the lowest planning echelon authorized to form and designate a series of targets. The series may be planned to support a limited attack, a final assault, a counterattack or a phased withdrawal. It should be planned to complement the supported commander's scheme of maneuver. It may be executed on call at a specific time, or when a certain event occurs. It is scheduled to start at 0.

Once a series is begun, targets and groups within the series are fired in a predetermined time sequence. Simultaneous attack of targets in a group within a series is as requested by the initiator or as determined by the FA fire planner. Attack is based on the nature of the targets and the desires of the force commander. Groups need not be fired as groups when fired as part of a series unless that is requested.

Graphically, a series is shown as individual and/or groups of targets within a prescribed area. The series is assigned a code name or a nickname.



The fact that a series of targets has been formed does not preclude the attack of individual targets and/or groups of targets within the series. A scheduling work sheet is prepared for each series of targets requested.



Illumination and/or Smoke. Some targets have a specified duration of fire, but the ammunition requirements are unknown;for example, smoke and illumination targets on which the expenditures are affected by wind speed and direction. Fire planners complete the illumination and/or smoke schedule as follows:

  • Indicate, by a horizontal line, the time on target and duration of fire (or desired effect).
  • Place the target number above this line.

  • Below the line, center a letter in parentheses keyed to a remark in the REMARKS column that shows the method of engagement (for example, two-gun illumination;lateral or range spread first rounds WP and HC, succeeding rounds HC).

  • When scheduling smoke, back off 1 minute to allow for buildup time (if using HC only and not WP for initial rounds). Buildup time is not to be used when firing on the same target. The maneuver commander must realize that because of weather, smoke fries cannot have guaranteed effects. When asking for smoke, the commander must be explicit in his intention. The FSCOORD must specifically look at alternative methods of achieving the intention if the smoke is not effective. This can be done by planning on-call HE targets to suppress selected areas.



Nuclear Schedules. The preparation of a nuclear schedule differs in several ways from that of a conventional schedule. The nuclear schedule is normally developed by a target analyst in the FSE (corps, division, or sometimes brigade). A summary of the nuclear target analysis is produced. It indicates all units that can achieve adequate coverage on each target (unit is within range, and coverage meets commander's guidance). The summary of analysis is then used to select the best combination of units and weapons and/or yields to fire on each target in the target complex. The range to target may be based on actual range or on a planning range (normally two-thirds of the maximum range of the weapon system). To ensure that the target analysis remains valid, the range to target used to develop the schedule is fired. This may be done by sending a warning order to the delivery unit indicating the target and a not-greater-than (NGT) range. The NGT range serves notice to the delivery unit or controlling headquarters that only those firing points at a range to the target less than the NGT range will be used to fire the missions. Thus, the delivery unit has complete flexibility and control in designating firing points while ensuring no degradation of desired effects on the target and no increases in minimum safe distances (MSDs) or collateral damage distances (CDDs). After firing units are assigned to targets, the sequence in which the targets will be fired in the schedule is determined. The effects that the environment of a nuclear battlefield (blast, thermal radiation, nuclear radiation, and electromagnetic pulse [EMP]) may have on friendly nuclear weapons are considered. One of the problems in scheduling nuclear weapons is preventing preinitiation. Preinitiation can be avoided by separating nuclear detonations in space and time and avoiding firing through the nuclear cloud of a previous burst. The detailed procedures for scheduling nuclear targets are explained in FM 101-31-2. The distances and waiting times that must separate nuclear bursts can be determined by using FM 101-31-2. Once total time is determined, it is subtracted from the time that the fires are to be completed. This indicates the time the nuclear targets will be fired.

MLRS FIRE PLANNING

Since MLRS fire planning procedures deviate in some ways from the traditional fire planning methods, MLRS fire planning is discussed separately. The different procedures are required because of the characteristics of the MLRS;its munitions, range capability, and volume of fire;and the MLRS employment doctrine (shoot-and-scoot tactics and the use of hide positions).

The MLRS can deliver a high volume of fire, in a short time over a large area to ranges of 30 kilometers. Therefore, MLRS fires are best used against targets that are one or more of the following:

  • Large targets.
  • Targets located with a large target location error.

  • Targets to which a high percentage of damage is desired.

  • Targets located beyond the range of cannon artillery.

The wide dispersion of the submunitions from the ICM warhead makes the MLRS an excellent weapon for attacking large or inaccurately located targets. The destructiveness of MLRS munitions makes MLRS well-suited for use against targets to which a high percentage of damage is desired. Because of its long range, MLRS can hit targets that are beyond the range of cannon artillery.

Ammunition resupply is a problem for all weapon systems, but it is a particularly important consideration for MLRS. Vast quantities of ammunition would be required to attack all targets of the types addressed above. Therefore, MLRS must be limited primarily to the attack of high-payoff targets.

The characteristics of high-payoff targets differ from operation to operation, depending on both enemy and friendly force postures;and targets will be determined through the targeting process. Targeting priorities for the MLRS should be as follows:

  • High-payoff targets 15 to 30 km from the FLOT.
  • High-payoff targets 0 to 15 km from the FLOT that cannon artillery cannot effectively engage.

  • Other targets 15 to 30 km from the FLOT.

  • Other targets 0 to 15 km from the FLOT that canon artillery cannot effectively engage.

To plan MLRS fires, the fire planner must understand the response posture system used for reporting the status of the MLRS unit's self-propelled launcher-loaders (SPLLs). They are designated as being in a hot, cool, or cold status by the MLRS battery FDC. Definitions and response times for the various response postures are shown below. This system helps the FDO select the MLRS launcher (or launchers) to fire a mission and helps the fire planner know the availability of MLRS fires.



The headquarters doing the fire planning for an MLRS unit must know how many launchers are currently in a hot status, how many launchers can be brought to a hot status, and how long it will take to bring them to a hot status.

When the fires of an MLRS unit are scheduled, each MLRS launcher is considered a firing unit. If all nine launchers in a battery were hot, then the scheduling work sheet would have nine lines for MLRS--one for each launcher. The FIRING UNITS column of the scheduling work sheet is left blank for MLRS units. The MLRS battery FDC selects the launcher to fire.

When scheduling the fires of MLRS units, fire planners should never plan more targets than the total number of launchers that can be brought to a hot status by the time the targets must be fired even if those targets use less than a full launcher load of rockets. Since a launcher can fire no more than 12 rockets per mission targets requiring more than 12 rockets must be scheduled for two or more launchers.

Because of the difficulty in accurately determining the amount of time required for an MLRS launcher to move from one firing position to another, each launcher is normally scheduled only once in a schedule of fires. If the schedule is long (more than 30 minutes) and the MLRS unit commander can give the fire planner an accurate estimate of the time it will take the launcher to move to a new firing position and be ready to fire (including time for ammunition resupply), a launcher may be scheduled to fire on more than one target. However, this situation is not expected to occur often.

When scheduling the fires of MLRS units, the fire planner should assume that a launcher in a cool status can be brought to a hot status, move to a firing position and be ready to fire within 10 l/2 minutes of being sent a fire mission. A launcher that is already in a hot status can be ready to fire within 3 minutes after it moves to the firing position.

There must be continuous coordination between fire planners and MLRS units to ensure that there are enough launchers in a hot or cool status to fire scheduled fires.

When a scheduling work sheet is prepared for the MLRS, lines are not used to show the duration of firing. Instead of lines, a dot is used between the target number and the number of rockets to be fired, regardless of how many rockets are fired or the duration of firing. The only exception to this rule is in the scheduling of groups when neither dots nor lines are used. Examples of remarks that might appear on a scheduling work sheet for MLRS are shown in the example scheduling work sheet for a preparation.



The designation of an NLT time on target gives the MLRS unit greater flexibility and eases its firing of the targets on the schedule. The time interval between rocket firings can be specified. This interval can be between 4.5 and 99.9 seconds. Even though the interval between rockets can be as long as 99.9 seconds, for reasons of survivability, the interval should be short enough that all rockets are fired within 2 minutes. If no interval is stated, the rockets will be fired at the maximum rate of fire, approximately 5 seconds between rockets.

Use of MLRS can be planned in the following schedules:

  • Counterpreparations.
  • Programs.

  • Series.

  • Groups.

  • Preparations.

Counterpreparations, Programs, and Series

These schedules are not normally fired at specific times. Instead they are fired on call and are usually keyed to a specific event or maneuver phase. (See the example scheduling work sheet for groups.)



When MLRS fires are planned on these schedules, a 3-minute buffer time (plus move time) is necessary for hot launchers and a 10 l/2-minute buffer time (plus move time) is needed for cool launchers. The buffer time for a hot launcher is needed because, before a launcher can fire, it must move from its hide position to a launch position, orient itself for location and direction, and compute firing data. The larger buffer time for a cool launcher is required to bring the launcher from a cool to a hot status.

Whenever possible, the MLRS unit should be given a not-before time and a not-after time between which to fire a target. This allows the MLRS FDC more flexibility in selecting a launcher to fire and a TOT for each target.

Because MLRS units normally fire only one target per launcher in a counterpreparation, the scheduling rules concerning gaps in the schedule and starting and ending the schedule with all units firing do not apply to the MLRS. However, the rules for phasing and refiring still apply.

The MLRS fires are usually directed at high-payoff targets. Therefore, the MLRS may be assigned targets that must be fired at a specific point in the counterprep rather than in the appropriate phase. Critical targets fired by the MLRS may be refired by cannon units (or in rare instances by another MLRS launcher). Normally, the MLRS will not refire targets originally fired by cannon units.



Groups

Groups may at times be scheduled for fire by MLRS units. (See the groups scheduling work sheet.) Groups must be planned with one or more launchers firing on each target. Also, MLRS and cannon units may be scheduled on targets in the same group;however, close coordination must be made between the cannon unit FDC and the MLRS unit FDC to ensure that the targets in the group are fired simultaneously. When given the order to fire the group, the MLRS FDC will fire the mission as a TOT mission, causing the fires to fall on all targets in the group at the same time. Only hot launchers should be scheduled to fire on a group of targets.

Preparations

Because preparations are keyed to a specific H-hour, MLRS units can fire at any predesignated time during the preparation. This also applies to programs and series. (See the preparation scheduling work sheet.)

Close coordination with the MLRS unit is necessary to ensure that enough launchers are in position to meet the TOTs specified in the preparation schedule. As with counterpreparations, all scheduling rules apply except those concerning gaps and starting and ending with all units firing.

Other Schedules

Programs of interdiction fires will normally be a series of TOT missions given to the MLRS battery. The not-before and not-after times discussed earlier can also be used.

The MLRS normally will not be assigned a mission that would cause its involvement in a quick-fire plan. Therefore, MLRS units rarely are included in a quick-fire plan. An additional limitation to involving the MLRS in a quick-fire plan is its inability to operate on more than one voice net and one digital external radio net. If MLRS is included in a quick-fire plan, the same techniques used to schedule a series should be used.


Section II

AUTOMATED FIRE PLANNING



The FA commander (as the FSCOORD) has the ultimate responsibility for responsive fire support. Therefore, he must be given the flexibility to manage the resources under his command. During fire planning operations, he manages his resources by specifying the fire units (FUs) that are to be used in the operation and the control under which they are to operate.

NONNUCLEAR FIRE PLAN COMMANDER'S CRITERIA

The successful execution of responsive fire support is the direct responsibility of the FA commander. He fulfills this responsibility through firepower and resource management. Since the available firepower and resources vary with the situation, the commander and his staff must be able to modify the standard computer solution as required. This is done by means of the nonnuclear fire plan (NNFP) modification file. Criteria manually entered in the NNFP MOD file are used by the computer in all NNFP processing. The file may be built from current or existing plans by use of the NNFP;COMD message.

Separate criteria files are established for each fire plan. If no MOD file is built for a specific plan, the current modification file established for tactical and technical fire control (TTFC) will be used. The NNFP MOD file criteria take precedence over the permanent criteria of the computer program. These criteria may be superseded in specific fire planning cases by means of the NNFP;INST input message. There are primarily five NNFP input messages used to enter the commander's criteria.

NNFP;MOD Message

The commander's criteria modification (NNFP;MOD) input message is used to establish criteria for all fire units in all fire planning functions. The modification and criteria are for planning purposes and will have no effect until the computation of the plan is initiated. For planning purposes, the message may be used as follows:

  • To ignore availability and type of ammunition.
  • To authorize use of standard met data during computations.

  • To designate the maximum number of battalions to attack a single target (div arty only).

  • To establish an effects cutoff factor.

It also allows the operator to associate the name of the battalion or div arty zone of responsibility with the fire plan.

NNFP;XCLUD Message

The commander's fire unit exclusion (NNFP;XCLUD) input message is used to exclude fire units by name or weapon type from planning consideration. The message can also be used to exclude specific types of ammunition (shell and/or fuze) by either weapon type or fire unit.

NNFP;ATTACK Message

The commander's attack method (NNFP;ATTACK) input message permits manual specification of desired effects or standard volleys to be fired against specific target types and degrees of protection.

NNFP;FUSEL Message

The commander's fire unit selection criteria (NNFP;FUSEL) input message is used as follows:

  • To associate fire units with a battalion.
  • To specify the maximum number of alleys to be fired by fire units with specified weapons.

  • To specify the ordering (FU selection) of fire units within a battalion.

At div arty, it is also used to specify the battalion assignment ordering number (BAON) to be used during computation of the fire plan.

NNFP;RESFU Message

The reserve fire units or interval (NNFP;RESFU) input message is used to reserve a designated fire unit for a specific time interval during a fire plan or to reserve all fire units for specific intervals of the fire plan period.

RELATED FILES

The commander's guidance for resource management is implemented by the establishment of appropriate computer files for each fire plan. The selected fire units and associated ammunition are provided by the ammunition and fire unit program and the fire support coordinating measures are provided by the support (SPRT) program. NNFP also accesses the artillery target intelligence (ATI), tactical fire control (TFC), and tactical and technical fire control (TTFC) programs for specific data and criteria.

Ammunition and Fire Unit Program

The AFU program provides for the maintenance of current information pertaining to the status, locations, strength, capabilities missions, and ammunition inventories of all associated fire units. This program provides supporting information for fire planning and for tactical fire control and technical fire control processing.

AFU;BUILD Message

The AFU;BUILD input message provides the means of associating AFU data with a fire plan. The data may be retrieved from either the current AFU file or from an existing fire plan file. Additions, modifications, and deletions can also be incorporated by using the AFU input messages (UPDATE, AMOUPD or BAMOUP, ASR, and so forth). There are four methods by which AFU data can be selected for fire planning:

  • The entire AFU file.
  • Individual fire units by name.

  • Weapons by type.

  • Fire units by ammunition type.

Regardless of the method used the existing AFU data will remain in both files until deletion.

Support Program

The SPRT program provides for the maintenance of current information pertaining to the status and location of all fire support coordinating measures. Generally, these measures are recommended by the FSCOORD and established by the force commander. Once developed, these measures are entered in the support routine and, when required, are associated with fire plans.

SPRT;BUILD Message

The SPRT;BUILD input message is used to construct a support planning file from either the current file or an existing planning file. Data to be included in the new plan can be designated by type (frontline trace [FRLT], no-fire line [NFL], final coordination line [FCL], and so forth) or by transferring all existing fire support coordinating measures to the new plan. Additions, modifications, and deletions can be incorporated by using the support program input messages (ZNE, GEOM, AIRCO, and COMD).

Artillery Target Intelligence Program

The ATI program is used by the div arty operations center and supported units to process target information received from all sources. The program correlates all target reports, combines reports when appropriate, and provides the most probable location of each target. The div arty computer can store 1,364 targets in the ATI file. Because the file contains all the gathered battlefield intelligence, it is the logical source for target data to be used for nonnuclear fire planning.

Tactical Fire Control Program

The TFC function at div arty provides automatic volume-of-fire computations for each target of the fire plan. For criteria not specified or established for a fire plan the data used are identical to those used for current TFC processing.

Tactical and Technical Fire Control Program

The TTFC program at battalion provides automatic computer processing of tactical fire control by determining the volume of fire necessary for defeating a target. Technical fire control computes the ballistic and firing solution. The TTFC program at battalion also controls the battalion target file that can contain up to 300 targets and is used for NNFP processing. For criteria not specifically established for a fire plan the data used are identical to those used for current TTFC processing.

TARGET LISTS

TACFIRE target lists are developed initially as described in the following paragraphs. They consist of the preliminary target list, fire plan target list, on-call target list, and targets in the schedule of fires.

Preliminary Target List

The preliminary target list is prepared from an accumulation of individually entered targets or from selected target data available from the ATI files at the div arty computer and individual targets entered with the NNFP;FPTU input message. When the div arty computer is available, FA battalions can get data from the ATI files. They request specific target types or designate a search area by using the ATI prepare fire plan (ATI;PREFP) input message and the ATI standing request for information (ATI;SRI). The FSO retrieval criteria should be obtained and consolidated before the ATI;PREFP message is submitted to div arty.

Once the preliminary target list has been coordinated with the maneuver commander and members of his staff, the FSO notifies the DS battalion operations element. Any special targeting instructions are forwarded along with the target number by means of the NNFP;INST message.

ATI;PREFP.The ATI;PREFP input message is the preferred means of developing a preliminary target list when the div arty computer is available. Details concerning this message are in TM's 11-7440-240-10-7 and 11-7440-241-10-7. After computer processing at div arty, the preliminary target list is transmitted to the requesting battalion and a copy is automatically distributed to each FSO according to MOI techniques. Target information retrieved from the ATI file is automatically stored, under the fire plan name, in the receiving unit's battalion target file. The entire target list is immediately available to the O&I personnel as well as to the FSOs at maneuver battalions and brigade. The FSOs then coordinate with the maneuver battalions and the brigade. By use of the NNFP;FPTU message, each FSO adds to or deletes from the list, as required to support his portion of the operation.

ATI;SRI. The ATI;SRI input message is used to establish criteria to be used by the div arty computer to retrieve targets that meet specific criteria. This ensures that the most recently acquired targets are available for addition to a specific fire plan. When possible, the submitted ATI;SRI should contain the identical criteria as those used in the ATI;PREFP input message. Targets retrieved can then be reviewed and, if desired, entered in the fire plan by use of the NNFP;FPTU message. Details concerning the ATI;SRI are in TM's 11-7440-240-10-8 and 11-7440-241-10-8.

Fire Plan Target List

A fire plan target list is a selection of targets from the preliminary target list that are designated as targets to be used in the fire plan schedule. Targets are moved from the preliminary target list to the fire plan target list by means of the NNFP;INST message. Scheduling instructions such as target priority, phasing and time to be fired are applied by using the NNFP;INST message. For each target listed in the fire plan target list the location type and/or subtype, degree of protection, size, and scheduling instructions are identified and stored.

On-Call Target List

An on-call target list is a selection of targets from the preliminary target list that are designated as on call. Targets are designated as on call in order to reduce the reaction time between the actual request for fire and the delivery of fires in the target area. Targets are designated as ONCALL by means of the NNFP;INST message.

Targets in the Schedule of Fires

Targets in the schedule of fires (TISF) are those fire plan targets that have been scheduled to be fired on in accordance with a time sequence or have been designated as on-call targets. Fire plan and on-call targets make up the TISF once the scheduling computations are completed. All the data that identified the target when it was in the fire plan target list remain with the target. In addition, all scheduling data to include firing unit, ammunition, specific H-hour, effects or volleys, and angle of fire, are identified with the target. The TISF make up the final target list established before execution of the fire plan.

Transmission of Target Lists

Any existing target list can be transmitted to any TACFIRE subscriber (except the DMD) by means of the NNFP;COMD input message.

SCHEDULING

The primary purpose of fire planning is to reduce reaction time and to establish a schedule of fires that will optimize the use of available fire units, the expenditure of ammunition, and the fire support provided to the maneuver forces. The nonnuclear fire planning function of TACFIRE provides a printed and detailed recommended solution to the target scheduling problem.

Primarily, there are two messages for controlling the fire plan scheduling solution: the nonnuclear fire plan target instruction (NNFP;INST) input message and the nonnuclear fire planning compute fire plan (NNFP;COMFP) input message. The NNFP;INST message deals with individual target instructions, such as when the target is to be fired and with what type of ammunition. The NNFP;COMFP message controls the overall fire plan parameters such as the duration and phasing. Each message affects the other, and together they determine the eventual fire plan solution.

NNFP;INST Message

The NNFP;INST input message permits scheduling instructions to be applied to each target in the preliminary target list. When target instructions are entered, the target then becomes a portion of either the fire plan target list or the on-call target list, depending on the instructions entered. Target instructions may be entered at any time after the target has been entered in the planning file for the specified plan. When the instruction message is entered the plan name must be entered in the PLAN field and the number of each target to which the instructions pertain must be entered in the TGTS field. Instructions for up to nine targets may be entered with one input message if the same instructions apply to all the targets specified.

Instructions that may be applied to specific targets include the following:

  • Designation as targets in the FPTGT or ONCALL lists.
  • Priority and phase to be applied to the target during scheduling.

  • Designation of time the target is to be engaged relative to H-hour.

  • The fire unit to engage the target if H-time is not specified (for more than one target).

  • The desired effects or volleys to be used against the target.

  • The shell, fuze, and angle of fire with which the target is to be engaged.

NNFP;COMFP Message

The NNFP;COMFP input message is used to control manually the conditions to be used in scheduling. These include the start time and length of phases for the fire plan and the target priorities to be considered in the computations.

BATTALION SCHEDULING PROCEDURES

Phase Start Time and Length

The NNFP function uses a variable interval scheduling technique to achieve a compact schedule. The time at which a target is scheduled is a function of fire unit availability. The duration of the attack on that target is a function of the number of volleys required to defeat the target, the fire unit reaction time, and the sustained rate of fire. If phase data are not entered in the NNFP;COMFP message, NNFP defaults to a one-phase fire plan with a maximum duration of 120 minutes. When phase data are entered, the duration is calculated from the phase start time and length information. Phase times, when specified, must not overlap, and combined they cannot exceed 120 minutes. If more than one phase is specified no phase can exceed 60 minutes.

Target Ordering

Before the scheduling portion of NNFP is entered, all fire plan and preliminary targets are ordered in accordance with the following consideration:

  • Priority.
  • H-time specified.

  • Repeat targets.

  • Phase.

Targets From the Preliminary Target List

These targets are scheduled after all fire plan targets have been tried. Targets from the preliminary target list are included in the computation if the FPLST field of the NNFP;COMFP message has been specified. Using the FPLST field is also a means of computing a hasty fire plan. These targets, considered the lowest priority targets in the fire plan use default instruction data (lowest priority, any phase, and so on). On-call targets are ordered last because they are not subject to the scheduling criteria.

Fire Unit Selection

Eligible fire units are obtained from the planning file. If a fire unit is mission essential data if its ready status is out, or if it is excluded by the NNFP MOD file, it is excluded from consideration.

Targets are retrieved from the ordered target list one at a time and are processed. The first (or next) target is compared with the fire unit list after the interval in which to begin scheduling of the target is established.

The eligible fire units for the plan are then selected for each target. If units to fire are specified for the target in the fire plan instructions, these fire units are considered first. If a fire unit is reserved or busy during an interval, it is excluded from consideration for the target for that interval. If the target is in a dead space area (DSA) or is out of range of the fire unit, that unit is excluded from the target. An ordering is then established for each fire unit for each target as follows:

  • Zone of reponsibility within which the target lies.
  • Fire unit ordering in accordance with the NNFP;FUSEL entries.

Variable Interval Scheduling

Scheduling begins when ordering has been completed for all targets. Use of the variable interval scheduling allows the computer to consider targets for scheduling on a 1-minute basis, with multiple fire units to initiate fire at the same time. Once a target has been scheduled, the fire unit is identified as busy until the time required to shoot the assigned volleys is elapsed. Time required is a function of the fire unit's sustained rate of fire plus its reaction time. This action allows fire units with a small volume of fire, or with a high sustained rate of fire, to engage other targets sooner than fire units firing on the same target with a larger volume of fire or a lower sustained rate of fire.

Minimum-Time Criteria

As soon as times are chosen for scheduling a given target, the fire units available at those times will be selected if they meet the minimum-time criteria. These criteria state that the fire unit must have time to fire one volley at the sustained rate of fire plus its reaction time. When a fire unit meets the minimum-time criteria, the maximum number of volleys (based on the sustained rate) that can be fired during the allowed time is calculated (the reaction time is taken into consideration). The duration allowed for a fire unit to fire is based on one of the following:

  • The interval between targets already scheduled for this fire unit.
  • The time from the start of the plan to the first scheduled target.

  • The time from the last scheduled target within a phase to the and of that phase.

  • The time from the last scheduled target within a plan to the and of that plan.

If this value is less than the maximum volleys value entered in the MOD file for the fire unit weapon, the calculated maximum volleys will be passed on to calculate the volume of fire. If it is not less, the maximum volleys listed in the MOD files will be used. Once a target has been scheduled, the fire units engaged are excluded from further consideration during the interval required to fire the assigned volleys. By use of the sustained rate of fire, the time to fire the assigned volleys is calculated. This time is then rounded up to the next higher minute, and the reaction time is added.

Repeat Targets

Repeat fire is indicated by the entry of more than one phase in the NNFP;INST message. The target is then scheduled in each specified phase with any combination of fire units. If the target cannot be scheduled in any of the specified phases, it is considered a scheduling exception.

H-Hour

An H-hour for the plan should be designated for computation since the scheduling is constructed relative to H-hour. Before final computations of the plan the actual H-hour may be specified to allow final printed output reports to include the actual H-hour.

Checks and Tests

Certain checks and tests are made on each target. The support function determines if the target location falls within the zone of fire of any artillery units. That function also will furnish the name of the zone (or adjacent zone at div arty) to the NNFP program. If the target is not within the battalion zone, or if it violates the NFL, the CFL, or an ACA the target will be scheduled;but a warning message will be generated.

RECOMMENDED COMPUTATION PROCEDURES

To attain maximum use of automated functions available for fire planning, at least two computations should be made when time is available. The first establishes the timing required. It also resolves any conflicts or exceptions that can be corrected through modification of target instructions, the modification file, reservations, available fire units, or computation instructions. The second computation can then obtain a realistic schedule that can be implemented.

First Computation

Generally, the only critical elements to be provided in the NNFP;COMFP message for the first computation are the plan and phase fields, which are temporary instructions. Fire plan computations should not be initiated until all the instructions for all the phases and priorities have been entered. The suggested approach for the initial computation is as follows:

  • Enter the plan name in the PLAN field and enter H-hour.
  • Enter the length of each phase established for the plan in the PHASE field. Phase lengths should reflect the percentage of total targets in each phase. Unless considered necessary, do not allow computation to default to 120 minutes (output will contain all 120 minutes).

The following information can be obtained as a result of the initial computation: (Output reports include NNFP;4214, 4215, 4216, 4217, 4218, and 4219.)

  • Length of time required to perform each phase of the plan.
  • Conflicts in the scheduling of individual targets as related to the relative time the target should be attacked.

  • Exceptions resulting from scheduling, capability, or ammunition limitations. Targets may be exceptions for more than one of the above reasons. However, only one exception will be listed with the order of listing as ammunition, capability, and scheduling.

  • Fire units assigned to each target and the effects achieved.

  • Ammunition used against each target.

From the available data many of the problems identified from the initial scheduling can be resolved through changes made in the target instructions by means of the NNFP;INST message. Other means by which to resolve the problems are:

  • Adding or deleting fire units or targets.
  • Changing fire unit reservations.

  • Changing the modification files.

  • Assigning specific times for targets to be engaged.

The output reports identify the time required to complete each phase of the fire plan. From this information the time to start each phase can be computed relative to H-hour.

Subsequent Computation

When all problems identified by the first computation have been resolved, a subsequent computation is initiated by use of the NNFP;COMFP message. The output reports derived from the subsequent request may be adequate, or they may require further modifcation.

NONNUCLEAR FIRE PLAN ALTERATION

After the fire plan has been computed and the schedule of fires reviewed changes may be required before execution. Major changes, such as adding targets or changing the duration of the phase lengths of a fire plan, require recomputation. Minor changes involve adding new fire units to targets, altering the time for firing on certain targets, or changing the method of attack. These minor changes can be incorporated without recomputing the fire plan. These changes can be made by use of the NNFP;FPA (fire plan alteration) input message.

EXECUTION

At battalion level, the term "execution,"when used in TACFIRE fire planning means determination of the ballistic solution for firing on each target. It does not imply that the weapons are actually fired.

The execute a fire plan (NNFP;EXECFP) input message allows battalions to execute a fire plan as a whole or by phases. Single phases or a combination of phases may be specified. Execution is accomplished only for those fire units associated with the executing battalion. After the fire commands have been computed, the fire command summary must be reviewed and screened for any air corridor or fire unit mask violations. When approved, the fire command summary is transmitted to the appropriate fire units. The time firing will begin is based on the H-time, as announced by the force commander. Each unit will start its portion of the schedule and attack each target at the time specified.

NONNUCLEAR FIRE PLANNING AUTOMATED RECORDS AND REPORTS

The nonnuclear fire planning program provides for a series of fire planning related reports. These reports are periodically printed on completion of a processing step or are printed on demand of fire planning personnel. The reports are immediately available to TACFIRE-equipped artillery units and fire support elements. The information in these reports will help the commander and his staff in conducting current operations and in planning for future operations. The reports and their sources are identified below.

NNFP;4211 Preliminary Target List

The preliminary target list is the initial target list acquired from the ATI files or by input of an NNFP;FPTU message. For each target listed the list provides target location, target type and/or subtype, degree of protection, target size, and target number. It also contains any other information available from the ATI files. The list is obtained as a result of input of an ATI;PREFP message, as a result of a request using the NNFP;COMD input message, or upon receipt from another computer center. Targets in the preliminary target list are received in the NNFP;XTGT format (TM's 11-7440-240-10-7 and 11-7440-241-10-7).

NNFP;4212 Fire Plan Target List

The fire plan target list is a selection of targets from the preliminary target list that are to be part of the fire plan solution. In addition to the data obtained from the preliminary target list the fire plan target list contains all scheduling instructions that have been applied to the target. The list is a result of receipt from another computer or a request using the NNFP;COMD message.

NNFP;4213 On-Call Target List

The on-call target list is a list of targets that have been designated as on call. This list shows the same information for each target as that shown in the fire plan target list. The list can be printed as a result of receipt from another computer center or by use of the NNFP;COMD message.

NNFP;4214 Schedule of Fires Report

The schedule of fires report provides scheduling results for each target in the fire plan. It also provides the status of each unit in the fire plan for the duration of the plan. A legend is printed at the start of each report defining the entries used in the report. The legend includes the following information;

  • Fire unit is idle.
  • Unit is firing.

  • Fire unit reaction time.

  • Nuclear target.

  • Unit is in a reserve status.

  • Number of volleys to be fired.

The output gives data by phase, by H-hour, and by fire unit. The report can be derived upon receipt from another computer center, by request using the NNFP;COMD message, or as a result of the NNFP;COMFP imput message.

NNFP;4215 Groups of Fires Report

The groups of fires report is provided for each group of fires in a fire plan. It contains the following:

  • The plan name.
  • H-hour if specified.

  • Target number.

  • Fire unit for each target.

  • Number of rounds for each target.

  • The scheduled time to repeat targets if applicable.

  • An on-call designator.

NNFP;4217 NNFP Ammo Report

The ammunition report summarizes the ammunition to be expended during the fire plan. At div arty, the report shows a battalion total by type. At battalion, the report shows total by fire unit. The report may be printed by using the NNFP;COMD message and will be printed upon completion of computations requested by using an NNFP;COMFP message.

NNFP;4218 Targets in the Schedule of Fires Report

The TISF report presents associated data for all targets in the fire plan. The scheduled fire plan targets are listed first and then all on-call targets. The data provided for each target include the following:

  • Location and description.
  • Zone in which the target is located.

  • Mission fired date (if previously engaged).

  • Any geometry, available supply rate (ASR), or ammunition level warnings.

  • H-hour, priority, and phase.

  • Group or series data (specified).

  • Desired and achieved effects or volleys.

  • Fire unit(s) assigned to the target.

  • Shell and fuze to be used by each fire unit.

The report can be received from another computer center or requested by using the NNFP;COMD message. It will be printed upon completion of fire plan computations requested by using the NNFP;COMFP message.

NNFP;4219 Fire Plan Summary Report

The fire plan summary report identifies the warnings and exceptions generated during the processing of a fire plan. It also provides a summary identifying the total number of targets in the fire plan, the number of scheduled and unscheduled targets, and the total number of targets with warnings. Each target is listed along with any warnings and--if there are warnings--the type of exception. The report can be printed by entry of the NNFP;COMD message. It is always printed upon completion of computations (NNFP;COMFP).

NNFP;4221 NNFP MOD List

The MOD list provides the contents of the MOD file associated with a specific plan name. It includes the following:

  • Data specified for ignoring ammunition.
  • The effects cutoff factor.

  • The maximum battalions to engage a target (div arty only).

  • The zone specified for use with the plan.

  • Fire unit selection criteria.

  • Maximum volleys by weapon type.

  • Fire unit, weapon and ammunition exclusions.

  • Any modifications to the standard attack table.

The MOD file is printed when a specific file is built with the NNFP;MOD message, and it can be printed by use of the NNFP;COMD message.

NNFP;4222 NNFP Count Report

The NNFP count report provides a count of the number of targets to be sent to a subscriber (or subscribers) when a fire plan list is sect. It is printed as a result of an operator request when an NNFP;COMD input message is entered.

NNFP;4223 Fire Command Summary

The fire command summary provides fire unit, H-hour, shell, lot, charge, fuze, volleys, deflection, time, and quadrant for each scheduled target and the appropriate data for on-call targets. It is printed or transmitted as a result of entry of an NNFP;EXECFP message.

NNFP;4224 Nuclear TISF Report

The nuclear TISF report lists the following data for each nuclear target scheduled to be fired:

  • Target number, location and description.
  • Phase and time (relative to H-hour) target is to be fired.

  • Zone(s) of target location.

  • Fire unit to engage target (launcher when applicable).

  • Weapon, shell, fuze, mark number, and yield of munition.

  • The number of rounds to be expended.

The report is output as a result of computation of a fire plan containing nuclear targets, or it may be printed by request using the NNFP;COMD message.

NNFP;4225 Mark Yield Summary

The mark yield summary lists, in addition to the plan name and H-hour, all fire units, by weapon type, mark, and yield, that are scheduled to fire nuclear munitions during the fire plan period. It is output as a result of computation of a fire plan that contains nuclear targets, or it may be printed by request using the NNFP;COMD message.

NNFP;4226 Nuclear Schedule of Fires Report

The nuclear schedule of fires report lists all nuclear targets to be engaged during the fire plan. Targets are listed by time relative to H-hour, firing unit, and target number. It is output as a result of computation of a tire plan that contains nuclear targets, or it may be requested by use of the NNFP;COMD message.

NNFP;4227 Fire Unit Reservation Report

This report lists fire unit reservations by fire unit, weapon, reservation type (nuclear or nonnuclear), and start and and times of reservation. It can be obtained by request using the NNFP;COMD message.

FILE MAINTENANCE

Although the storage capability of TACFIRE is extensive, it is possible to totally inundate the memories to a point that system functions become degraded. To preclude overextending the memory capabilities of the system, continual and thorough file maintenance must be performed.

Operations During Nonnuclear Fire Planning

When time permits, a count of the number of targets meeting fire plan criteria should be requested before submission of the target list request (ATI;PREFP). If target count is excessive, more stringent search criteria can be entered. The retrieval of an excessive number of targets meeting search criteria will do the following:

  • Cause critical planning time to be wasted due to the necessity for review before selection of the targets for inclusion in the plan.
  • Result in tying up communications nets for an excessive amount of time. This allows the enemy additional time for the conduct of electronic warfare (jamming, intrusion, and so forth).

  • Cause targets to be printed only (not stored) at the receiving computer center if the number exceeds 150 (maximum targets in a fire plan). If any of the targets not stored are to be included in the fire plan, they must be associated with the fire plan by a separate entry of an NNFP;FFTU message for each target.

Targets in the preliminary target list that are not to be included in the fire plan are deleted. This is done by entering the NNFP;FPTU message with the DELETE and TGTS mnemonics specified. Targets that should be deleted are those that--

  • Are duplicated.
  • Are out of range of all available fire units.

  • Are no longer appropriate for attack (for example, behind friendly forces).

  • For some other reason, do not meet the criteria for attack during conduct of the fire plan.

Once instructions have been applied to targets selected for the fire plan, the complete preliminary target list can be deleted by initiating an NNFP;COMD message with the PLAN, DELETE, and FPLST mnemonics specified.

Specific data (on-call targets, targets in the schedule of fires, and so on) can be selectively deleted from a fire plan by entry of the data and the DELETE mnemonic in the FFPF;COMD message.

Rescinding, Superseding, or Modifying an OPORD or OPLAN

If an OPORD or OPLAN is rescinded, superseded or modified before execution by the maneuver force, the following actions should be taken at the FCE or FDC:

  • Delete that portion of the fire plan no longer needed by specifying the appropriate entries (as in the preceding paragraphs) in the NNFP;COMD input message.
  • If the plan is cancelled, delete the entire plan (including related files) by entry of the PLAN and PURGE mnemonics in the NNFP;COMD input message.
  • If abort (halting a computer action before completion of a task) is initiated during a search or computation, verify the files to ensure that unnecessary data are eliminated. This may entail the deletion of individual targets, lists of targets, and/or files related to a specific fire plan.

Actions After Completion (Firing) of a Specific Plan

After a plan has been fired, all data, including related files, should be deleted from the computer files by entry of the PLAN and PURGE mnemonics of the NNFP;COMD input message.

VERIFICATION

To ensure that computer files exist for active fire plans only, a copy of the master plan list (MPLIST) can be obtained by use of the system miscellaneous input message (SYS;MISC) with the MPLIST mnemonic specified. The output message will list all the plans that exist within the computer and will also include the related files for each plan (AFU, SPRT, NNFP, and FSE).
