CHAPTER 7

FIRE COMMANDS AND FIRING REPORTS


7-1. DEFINITIONS

Fire commands are used by the FDC to give the howitzer sections all the information necessary to start, conduct, and cease firing. In a battery without BCS, fire commands must be sent by voice. In a battery using BCS, fire commands are sent digitally from the computer to the gun display unit (GDU) at the howitzer. Initial fire commands include all elements necessary for orienting, loading, and firing the piece. Subsequent fire commands must include only those elements that have changed, except quadrant elevation. Quadrant elevation is given in every fire command and allows the howitzer section to load and fire, if in a when ready (WR) status.

Note: Section chiefs must completely view the entire digital fire command on every round. In the race to be first, they may look only at charge, deflection, and quadrant elevation. This creates obvious problems when the fire for effect (FFE) is entered or if shell, fuze, and fuze setting are changed.

7-2. SEQUENCE OF FIRE COMMANDS

a. The elements of a fire command are always given in the same sequence (Table 7-1). This saves time and confusion; each member of the section knows the sequence and can anticipate what is coming next. This sequence allows actions to occur at the same time. For example, the propellant charge can be cut and the fuze set (if required) while the deflection and quadrant are being set.

b. Certain elements of the fire command may be standard and these need not be sent on each subsequent fire command. Quadrant elevation may never be standardized. It is given in each fire command.

7-3. TYPES OF FIRE COMMANDS

a. Digital fire Commands. Digital fire commands are used by units equipped with BCS. The entire fire command is displayed on the section chiefs assembly (SCA). Also the deflection is displayed on the gunner's gun assembly (GA) and the quadrant elevation is displayed on the assistant gunner's GA. The section chief, however, still announces the entire fire command, including the deflection and quadrant. As a data check, the gunner and assistant gunner read back the deflection and quadrant. The section chief can recall specific parts of the fire command by depressing the appropriate key on the SCA. (See Appendix L.)

b. Voice fire Commands. Voice fire commands are used by units without BCS, or in the event the equipment fails to function properly. To facilitate the use of voice commands, the FDC will provide the fire command standards to the section chief when the unit first occupies the position. Fire command standards are discussed in more detail in paragraph 7-24.

c. Degraded Digital Communications. For BCS-equipped units, digital communications are the primary means for transmitting fire commands. If lost or degraded, communications should be reestablished as soon as possible. A solution to degraded digital communications is to use the BCS purely as a technical fire direction computer and send the data by voice.

(1) If one howitzer in the battery or platoon loses digital communications, the FDC sends voice commands to that howitzer. (All parties should try to reestablish the digital capability.)

(2) If two or more howitzers lose digital communications, the battery or platoon notifies them by voice to go to the degraded GDU mode. The howitzers will ignore GDU data and take all voice fire commands.

(3) In the degraded GDU mode, the FDC may compute data, deflection and quadrant, from the base piece to center of target and send data to the guns by voice.

(a) If the FDC uses TGPCs, these will be applied and used until the command CANCEL TGPCs is given by the FDC. This command is usually given after digital communications are reestablished.

(b) Time permitting, FDC will send firing data for each individual howitzer. When this occurs, FFE may be AT MY COMMAND (AMC) to maintain the element of surprise and achieve maximum effect on the target.

7-4. ELEMENTS OF THE FIRE COMMAND

The elements of the fire command are discussed in paragraphs 7-5 through 7-15 below.

7-5. WARNING ORDER

A warning order is always announced to alert the firing unit to the mission. In a BCS-equipped battery, the warning order is a steady alarm signal from the case assembly of the GDU, which indicates the start of the fire mission. The section chief depresses the cycle key of his SCA to silence the alarm and acknowledge the receipt of fire commands. When a firing battery is using voice commands, a warning order of FIRE MISSION is announced. The warning order is not given in subsequent commands.

7-6. PIECES TO FOLLOW, PIECES TO FIRE, AND METHOD OF FIRE

This element designates the weapons that will follow the mission, the weapon(s) that will fire initially, and how they will engage the target.

a. Pieces to follow tells the platoon who will follow the commands given for an adjust-fire mission. BATTERY ADJUST or PLATOON ADJUST indicates that the mission will be an adjust-fire mission and that all weapons will copy the commands, follow the mission, and participate in the FFE phase. Any weapon or number of weapons may be announced in this element; for example, PLATOON ADJUST or NUMBER 1 AND NUMBER 3 ADJUST. In a BCS-equipped unit, the do not load (DNL) indicator bars will be lit on the SCAs of those howitzers that are to follow the mission. If the mission is an FFE mission, pieces to follow is not given.

b. Pieces to fire indicates which weapon(s) will fire the data given in the initial fire command. PLATOON ADJUST, NUMBER 3 indicates that during an adjust-fire mission, Number 3 will fire the initial round of adjustment.

(1) In a BCS-equipped unit, the SCA of the piece(s) to fire, (Number 3 in this example), would show 1RD ADJ and the double indicator bars under the word FIRE would light.

(2) A voice command would be NUMBER 3, 1 ROUND.

(3) If the mission were fire for effect, then PLATOON would be sent.

c. Method of fire tells the firing piece(s) how many rounds to fire. PLATOON ADJUST, NUMBER 3, 1 ROUND indicates that during this adjust-fire mission Number 3 will fire one round at the data given in the initial fire command. PLATOON 1 ROUND indicates a FFE mission with all weapons firing one round at the data given in the initial fire command.

7-7. SPECIAL INSTRUCTIONS

Special instructions are used when actions that are different from normal are required. Within the BCS-equipped battery, restrictive commands (DO NOT LOAD or AT MY COMMAND) are signified by the double indicator bars under DNL or AMC on the SCA. Other special instructions such as high angle, (use) gunner's quadrant, azimuth, or zone and/or sweep fire, will be displayed as digital readout in the window of the SCA when the special instruction key of the SCA is depressed. When voice commands are used, the FDC must announce the special instruction(s) to be followed. The FDC will precede a special instruction with the words SPECIAL INSTRUCTIONS. When more than one special instruction applies, restrictive commands should be announced first.

a. DO NOT LOAD is a restrictive fire command that prohibits loading and firing. The section may prepare the projectile, charge, and fuze (if applicable) and lay the howitzer or deflection; and set the quadrant elevation (or loading elevation).

(1) Digital. Double bars are lit under DNL on the SCA. When the round is to be fired, the double bars under FIRE on the SCA are lit and the audible alarm sounds. The section chief announces CANCEL DO NOT LOAD, QUADRANT (so much). The howitzer is fired at the section chief's command unless otherwise restricted.

(2) Voice. The command from the FDC would be (so many) ROUNDS, (special instruction) DO NOT LOAD. To fire the rounds, the FDC commands CANCEL DO NOT LOAD, QUADRANT (so much). This command allows the guns to load if not otherwise restricted by special instructions. The target number may be used in place of the command QUADRANT to allow loading and firing of preplanned targets and scheduled fires. DO NOT LOAD does not apply to the entire mission, it must be announced with each initial or subsequent command.

Note: DO NOT LOAD is a standard special instruction in a Copperhead priority mission. The Copperhead target of opportunity mission is AT MY COMMAND.

b. AT MY COMMAND (or BY PIECE BY ROUND AT MY COMMAND) is a restrictive command that prohibits the battery from firing until directed to do so by the FDC.

(1) Digital. Double bars under AMC on the SCA are lit. When the section is laid, the section chief presses the READY key at the SCA. When the round is to be fired the double bar under FIRE lights and the alarm sounds.

(2) Voice. The command from the FDC would be (so many) ROUNDS, SPECIAL INSTRUCTIONS AT MY COMMAND. When directed to fire the rounds, the section(s) would fire all the rounds specified in the method of fire. The command BY PIECE AT MY COMMAND would direct the sections to fire all the rounds specified in the method of fire by section(s) as announced by the FDC. The command BY ROUND, AT MY COMMAND would direct the section(s) to fire each of the rounds in the method of fire by volley as commanded by the FDC. The command BY PIECE, BY ROUND, AT MY COMMAND combines the control of both commands explained above. AT MY COMMAND remains in effect until the FDC commands CANCEL AT MY COMMAND (or BY PIECE or BY ROUND AT MY COMMAND). AT MY COMMAND may be cancelled at any time. If the FDC has announced QUADRANT, the command would be CANCEL AT MY COMMAND, QUADRANT (so much).

c. HIGH ANGLE is announced, or displayed as HA on the SCA, to alert the section that the mission is to be fired at an angle of elevation greater than 800 mils. Light artillery weapons can be elevated before loading. Medium and heavy artillery weapons normally must be loaded at loading elevation.

d. USE GUNNER'S QUADRANT is announced, or displayed as GQ on the SCA, when the FDC desires the gunner's quadrant be used to set or check quadrant elevation. This is more often used when firing danger close or precision fire missions, which require greater accuracy.

e. AZIMUTH is announced, or displayed as AZ on the SCA, to alert the sections to a large shit in the direction of fire. The command AZIMUTH will be followed by the azimuth in mils.

f. SWEEP (so many) MILS, (so many) DEFLECTIONS commands a method of fire used when the standard sheaf does not adequately cover the target and more width is required. Sweep fire provides for firing several deflections with one quadrant.

(1) Digital. A sample SCA display for sweep fire is S 105D, which indicates sweep 10 mils, 5 deflections.

(2) Voice. A sample command is SWEEP 10 MILS, 5 DEFLECTIONS. The section chief computes the required deflections and, after firing the displayed deflection, fires the remaining deflections in any order or as directed by unit SOP.

g. ZONE (so many) MILS, (so many) QUADRANTS commands a method of fire used when the standard sheaf does not adequately cover the target and more depth is required. Zone fire provides for firing one deflection with several quadrants.

(1) Digital. A sample SCA display for zone fire is Z 53QE; that is, zone, 5 mils, 3 quadrant elevations.

(2) Voice. A sample command is ZONE, 5 MILS, 3 QUADRANTS. The section chief computes the required quadrant, fires the initial quadrant, and then fires the remaining quadrants in any order or as directed by unit SOP.

h. SWEEP (so many) MILS, (so many) DEFLECTIONS, ZONE (so many) MILS, (so many) QUADRANTS commands a method of fire combining sweep fire and zone fire. Sweep and zone fire provides for firing several deflections and quadrants. On the SCA, the command is displayed in the order listed above as the chief of section presses the cycle key (that is, S DF, Z QE). The chief of section fires the displayed commands for deflection and quadrant first and then fires all combinations of computed deflections and quadrants, in any order or as directed by unit SOP.

i. SPECIAL CORRECTIONS is announced or displayed on the SCA to alert the crew when a separate time, deflection, and/or quadrant will be sent to or fired by one or more gun sections.

(1) The words SPECIAL CORRECTION(S) should precede any special corrections that apply in the fire command. This command prevents misunderstanding and unnecessary repetition of missed special corrections. If SPECIAL CORRECTIONS is announced alone, it alerts the sections that separate data will be sent to one or more sections. Unit SOP and degree or training dictate how this should be implemented.

(2) SPECIAL CORRECTION, NUMBER (so-and-so) LEFT or RIGHT (so many mils) may be announced. These corrections are applied by the specified piece to the announced deflection and remain in effect until changed (within a fire mission) or until the command END OF MISSION is given. This command may be given administratively, apart from fire commands; or it may be announced in the special instructions element of a fire command. These corrections are in addition to any corrections currently on the gunner's aid.

(3) SPECIAL CORRECTION ON NUMBER (so-and-so), OPEN or CLOSE (so many mils) may be announced. Each piece (other than the piece specified) applies a correction to the announced deflection on the gunner's aid. Each section chief determines his correction by multiplying the number of mils announced by the number of pieces his piece is removed from the piece announced. For example, the command ON NUMBER 3, CLOSE 4 is given. Number 3 applies no correction. Number 1 applies let 8. Number 2 applies let 4. Number 4 applies right 4. All guns fire the announced deflection after applying their corrections to the gunner's aid. These corrections are applied to any corrections already on the gunner's aid and remain in effect until changed (within a fire mission) or until the command END of MISSION is given.

(4) SPECIAL CORRECTIONS, (LEFT, CENTER, or RIGHT) SECTOR is announced when terrain gun position corrections for other than the primary sector are being used. If TGPCs are computed, the corrections for primary sector are set on the gunner's aid of all weapons. These corrections are announced administratively and recorded on the DA Form 5212-R. To change sectors, the FDC commands (LEFT, CENTER or RIGHT) SECTOR. Upon termination of the mission, the howitzer sections reapply the corrections that were in effect before the mission.

(5) CANCEL TERRAIN CORRECTIONS indicates that all howitzer sections are to set their gunner's aid counters to zero. At the end of the mission, the TGPCs that were in effect before the mission (usually the primary sector) will be reapplied unless the FDC directs otherwise.

7-8. PROJECTILE

This element designates the type of projectile to be used in the fire mission. The type of projectile that is to be prepared and loaded is always displayed in the SCA. When voice fire commands are being used, the projectile must be announced when it differs from standard.

7-9. AMMUNITION LOT

Ammunition lot numbers should be coded for simplicity. Separate-loading ammunition has two designators-the first letter for projectile and the second letter for the propellant. Semifixed ammunition has only a one-letter designation. The lot designators are automatically displayed at the SCA. When voice fire commands are used, the lot designators must be announced when they differ from standard.

Note: Large-quantity lots are normally set aside to be fired during registrations and missions when more uniform effect is important. Small-quantity lots should be used for missions when uniformed effect is not critical. Each section will segregate ammunition by lot and keep accurate record on DA Form 4513.

7-10. CHARGE

The charge indicates the amount of propellant to be used and grants permission for the crew to cut the propellant. Charge is automatically displayed on the SCA or announced by the FDC. It is never standardized.

7-11. FUZE

The required fuze type is announced (or example, FUZE TIME) or displayed on the SCA. The section chief announces the fuze displayed on SCA. Fuze is announced in subsequent command only when a change in type is desired.

Note: The GDU does not distinguish between M564 and M582 mechanical time superquick (MTSQ) fuzes displayed on the SCA. Unit SOPs must be established if both fuzes are used for the same mission.

7-12. FUZE SETTING

If fuze quick is to be fired on the delay mode, DELAY is announced by the FDC or displayed on the SCA. If the fuze is a mechanical type (MT), MTSQ, or proximity (VT) faze, the fuze setting is displayed automatically on the SCA. Voice commands are announced; for example, FUZE TIME, TIME 17.6 or FUZE VT, TIME 17.0.

Note: If shell DPICM is to be fired in the self-registration mode (SR), fuze setting black triangle 98.0 must be announced; for example, SHELL DPICM-SR, LOT DG, CHARGE 4, FUZE TI, TIME BLACK TRIANGLE 98.0.

7-13. DEFLECTION

With voice commands, deflection is always announced as our digits; for example, DEFLECTION 0321 (zero three two one) and DEFLECTION 3300 (three three hundred). Normally, deflection is displayed on the SCA as a four digit value. If three numbers appear, assume the first number is a zero. The section chief announces deflection using our numbers. The gunner sets the announced, or displayed, deflection on the panoramic telescope and traverses the tube until he has a correct sight picture on the proper aiming point (two step deflection method). When the section chief announces deflection, the gunner reads back the deflection. After the assistant gunner (AG) has reported QUADRANT (so much), SET, the gunner will verify his sight picture, ensure that his bubbles are centered, and reports DEFLECTION (so much), READY.

7-14. QUADRANT ELEVATION

a. Quadrant elevation gives the section chief permission to load and fire the round unless otherwise restricted by special instructions or unsafe conditions. The AG sets of DA Form 4513 the quadrant elevation announced by the FDC, or displayed on his gun assembly (or example, QUADRANT 318). He elevates the tube to that quadrant elevation after the projectile has been loaded. When the section chief announces quadrant, the AG reads back the quadrant that is set on the range quadrant. After the AG has centered the bubbles on the range quadrant, he reports QUADRANT (so much), SET.

b. To increase responsiveness, loading procedures may be changed per the unit SOP, as follows:

(1) Round is loaded on deflection. This procedure can be used when loading will not interfere with receipt of the remaining fire commands.

(2) Adjusting piece loads subsequent rounds immediately after firing. This loading method can be used for all projectile-fuze combinations not using a mechanical time fuze. It is possible that the adjusting piece may not have the correct projectile-fuze combination loaded when entering FFE. If this occurs, the loaded round is fired and the remaining FFE rounds are fired with the correct projectile-fuze combination. At the end of the mission, the chief of section reports to the FDC that his howitzer fired ammunition not specified in the fire command.

EXAMPLE

Suppose the fire command was 3 ROUNDS VT IN EFFECT. Number 4 fired one round with fuze quick and two rounds with fuze VT. The chief of section reported NUMBER 4 FIRED 1 QUICK AND 2 VT IN EFFECT. The FDC then updates the ammunition count accordingly.

CAUTION
Do not leave rounds in a hot or warm tube for a period longer than that specified by the technical manual for the weapon.

(3) Nonadjusting pieces load the shell to be fired in effect on receipt of the initial fire command. This procedure also applies to all projectile-fuze combinations not using a mechanical time or VT fuzes. When fuze VT is to be fired in effect, the FDC calculates the VT fuze setting corresponding to the initial target location and sends it to the nonadjusting pieces. If terrain, weather, and enemy capabilities permit, the FDC can, in wartime, send the VT minimum safe time to the nonadjusting pieces.

Note: If a howitzer has automatically reloaded during the adjust phase and END of MISSION is announced before the FFE phase, the following precautions should be taken:

  • Leave weapon laid on last fired data.
  • Announce to FDC NUMBER (so-and-so) IS LOADED.
  • Evaluate hot or cold tube situation.
  • Decide to compute safe data to shoot round, or unload weapon.

7-15. METHOD of FIRE OR EFFECT

This element indicates the number of rounds and type of ammunition to be used in effect. When applicable, it is announced in the initial fire command after the quadrant and must be announced before the last subsequent command in an adjust fire mission. This is displayed automatically on the SCA. With voice commands, it is announced after quadrant elevation; for example, 2 ROUNDS, FUZE VT IN EFFECT.

7-16. SPECIAL METHODS OF FIRE

There are voice fire commands that cannot be displayed on the GDU SCA. Shown below are the commands and their definitions.

a. CONTINUOUS FIRE is given when it is desfired that the howitzer crews continue to fire within the prescribed rates of fire for their howitzer until the command CHECK FIRING or CEASE LOADING is given.

b. FIRE AT WILL is used in a direct fire role, primarily for perimeter defense. The command is TARGET (so-and-so), FIRE AT WILL. Howitzer crews fire under the control of their section chief.

7-17. CHECK FIRING

The command CHECK FIRING can be given by anyone, but it should be used only in emergencies or if a safety violation is noted. All firing ceases immediately. The command may be given by voice, displayed on the SCA, and/or given by hand signals all at the same time. Immediate action must be taken to determine the nature of the check fire and to correct the situation.

Note: To give the hand signal, raise your hand in front of your forehead, palm to the front, and swing your hand and forearm up and down several times in front of your face.

7-18. CEASE LOADING

The command CEASE LOADING allows the firing battery to fire rounds that have already been loaded, but no additional rounds may be loaded. It is a voice command only, with the exception of final protective fire (FPF) missions processed with BCS.

7-19. END of MISSION

The command END OF MISSION (EOM) means that the fire mission has been terminated. The howitzer sections should return to the azimuth of lay or priority target data. The SCA displays EOM for that howitzer; for example, GUN (number so-and-so) EOM.

7-20. PLANNED TARGETS

a. The battery may be assigned planned targets for which current firing data must be maintained. Each target is assigned a number and each weapon is laid on its assigned priority target. In such cases, unit SOP usually designates a command or a prearranged signal to fire on the priority target, bypassing the usual sequence of fire commands.

EXAMPLE

Target AC7343 has been designated as a priority target. Firing data have been computed and have been transmitted to one of the firing platoons. On the command RIGHT, SUPPRESS AC7343, the right platoon engages Target AC7343 with the previously arranged method of fire.

b. In defensive operations, the command FIRE THE FPF causes the firing battery to fire the final protective fires on which it is laid.

7-21. REPETITION AND CORRECTION OF FIRE COMMANDS

a. One section (normally the adjusting piece) of the firing unit should be designated to read back all voice fire commands to ensure that the howitzer sections have received the fire commands correctly. When a command has not been heard or has been misunderstood, the request for repetition is stated as a question; for example, DEFLECTION NUMBER 2? When the FDC replies, the repetition of a command is always preceded by NUMBER (so-and-so), THE COMMAND WAS; for example, NUMBER 2, THE COMMAND WAS DEFLECTION 2768.

b. If an incorrect command has been given, but the command QUADRANT has not been announced, the FDC commands CORRECTION followed by the correct command and all subsequent elements. If QUADRANT has been announced, the FDC commands CHECK FIRING. CANCEL CHECK FIRING is announced followed by the corrected element and all subsequent elements.

7-22. FIRING REPORTS

The section chief reports to the FDC all actions that affect the firing of his weapon in support of the battery mission. During firing, the following specific reports are made:

a. When the special instruction DO NOT LOAD has been commanded by the FDC the section chief reports LAID, NUMBER (so-and-so). This report is sent when the projectile, charge, and fuze (if applicable) have been prepared; the howitzer has been laid for deflection; and the quadrant (or loading elevation) has been set.

b. When the special instruction AT MY COMMAND or BY PIECE (or BY ROUND) AT MY COMMAND has been commanded by the FDC, the section chief reports by voice READY, NUMBER (so-and-so). This report is sent when the section is ready to fire (in compliance with the fire command). The report is sent digitally by pressing the READY key on the SCA.

c. In voice operations, SHOT NUMBER (so-and-so) is reported after each round has been fired. If, however, the method of fire is more than one round, SHOT is announced only after the initial round. For GDU-equipped howitzers, the report is sent digitally when the section chief presses the SHOT/RC key once on the SCA.

d. ROUNDS COMPLETE NUMBER (so-and-so) is announced when the final round designated in the method of fire has been fired. If, however, only one round is to be fired, ROUNDS COMPLETE will not be reported after SHOT. For GDU-equipped howitzers, the report of rounds complete (RC) is sent when the SHOT/RC key on the SCA is pressed a second time. For a GDU-equipped howitzer to receive subsequent fire commands in any mission, rounds complete must be transmitted to the FDC.

e. MISFIRE NUMBER (so-and-so) is announced when a misfire has occurred (voice only).

f. Ammunition status is reported. The number of rounds expended, by type and lot number, is reported when requested by the FDC (voice or per unit SOP).

g. Data fired in error are reported. The chief of section reports to FDC the actual data fired in error; for example, NUMBER 2 FIRED DEFLECTION (so much).

7-23. STANDARDIZING ELEMENTS OF THE FIRE COMMAND

Certain elements of fire commands may be standardized after the tactical situation, weapon, and personnel capabilities, ammunition status, and enemy counterfire threat have been considered. As shown in Table 7-1, the following elements of the fire command may be designated as standard: pieces to follow, pieces to fire, method of fire, projectile, ammunition lot, and fuze. If the DO decides to vary from fire command standard data, he must administratively cancel the existing standard and issue the replacement standard data. Only one set of standard data can be in effect at any particular time. Once standard data are placed in effect, the platoon will fire the standard data unless the fire command specifies something different.

EXAMPLE

The FDO or platoon leader considers the tactical situation and the other actors mentioned above and determines that the fire command elements designated as standard should be as follows:

  • Pieces to fire and method of fire: Number 3, 1 round.
  • Projectile: HE.
  • Ammunition lot: XY.
  • Fuze: Quick.

These standards tell the firing battery or platoon that if not stated in a fire command, the piece to fire will be Number 3, and the method of fire will be one round, shell HE, lot XY, and fuze quick.

7-24. EXAMPLE OF FIRE COMMANDS

a. Nonstandard Adjust-Fire Mission. In this example, no standard elements are used. (See figure 7-4.)

FIRE MISSION, PLATOON ADJUST, NUMBER 3, 1 ROUND, SHELL HE, LOT XY, CHARGE 4, FUZE QUICK, DEFLECTION 3024, QUADRANT 247, 2 ROUNDS IN EFFECT.

(1) Number 3 is announced as the adjusting weapon. It fires one round (shell HE, lot XY, fuze quick) with the announced charge, and at the announced deflection, and quadrant. The rest of the platoon prepares 2 HE rounds with fuze quick and follow the fire mission.

(2) The first subsequent fire command is as follows:

DEFLECTION 2978, QUADRANT 218.

Number 3 fires one round (shell HE, lot XY, charge 4, fuze quick) at the new deflection and quadrant.

(3) The second subsequent fire command is as follows:

PLATOON 2 ROUNDS, DEFLECTION 2950, QUADRANT 210.

The entire platoon fires two rounds at the announced deflection and quadrant. END OF MISSION is commanded as appropriate. At END of MISSION, an ammunition update is required as shown in figure 7-4.

b. Nonstandard FFE Mission. In this example, no standard elements are used:

FIRE MISSION, NUMBER 3 AND NUMBER 4, 3 ROUNDS, SHELL WP, LOT DY, CHARGE 7, FUZE QUICK, DEFLECTION 2870, QUADRANT 320.

Number 3 and Number 4 each fire three rounds as commanded. END OF MISSION is commanded as appropriate, and ammunition expended is updated (see figure 7-4).

c. Standard Adjust-fire Mission. Elements designated as standard in this example are Number 3 firing one round in adjustment, shell HE, lot XY, and fuze quick:

FIRE MISSION, PLATOON ADJUST, CHARGE 4, DEFLECTION 3024, QUADRANT 247, 2 ROUNDS IN EFFECT.

(1) Number 3 fires one round (shell HE, lot XY, fuze quick) with the announced charge, and at the announced deflection and quadrant. Nonadjusting pieces prepare two rounds of HE and follow commands. Adjustment continues as in the first example.

(2) When fire for effect is entered, the commands are:

PLATOON 2 ROUNDS, DEFLFECTION 2950, QUADRANT 210.

(3) The entire platoon fires two rounds of shell HE at the announced deflection, and quadrant. END OF MISSION is commanded as appropriate.

Note: At END OF MISSION an ammunition update is required as illustrated in figure 7-5.

d. Standard FFE mission. Elements designated as standard in this example are Number 3, one round, shell HE, lot XY, and fuze quick.

FIRE MISSION, PLATOON 3 ROUNDS, CHARGE 4, DEFLECTION 3111, QUADRANT 400.

Each weapon in the platoon fires three rounds (shell HE, lot XY, fuze quick) with the announced charge, and at the announced deflection and quadrant. END OF MISSION is commanded as appropriate, and ammunition is updated (see figure 7-5).

7-25. RECORD OF MISSIONS FIRED

a. The DA Form 4513 or 4513-R is used by each section to record fire commands (digital or voice), ammunition stock (on hand, fired, transferred or resupplied), and any standardized data. After this form has been completed, it is used primarily or computing remaining tube lie on the DA Form 2408-4. All elements, of this form must be recorded neatly and accurately.

Note: A reproducible copy of DA Form 4513-R is located at the back of this manual.

b. The form consists of our basic parts. They are the administrative data (to include standard data), AMMUNITION/FUZES ON HAND, the fire mission data (to include transfer and resupply) and AMMUNITION EXPENDED. Each of these parts should have the following information recorded (see figures 7-4 and 7-5):

(1) Administrative data

(a) SECTION-howitzer bumper number/position number in formation.

(b) DATE-date of firing.

(c) PAGE OF-each side of the form represents one page of the total pages for that days firing.

(d) STND DATA-elements of a fire command standardized in order to expedite the delivery of fires.

    • ADJ PIECE-howitzer designated as adjusting piece (voice commands only) and number of rounds to be fired.
    • SH-type of shell used in adjustment.
    • LOT-designated lot of projectile and propellant. Lot designators are usually established by the platoon leader or fire direction officer.
    • FZ-type of fuze used in adjustment.

(2) AMMUNITION/FUZES ON HAND

(a) On the first line, enter the type of ammunition.

(b) On the second line, list lot designators for projectiles, propellants, fuzes, and the primer nomenclature. Projectiles and propellants are recorded separately for separate-loading ammunition.

(c) On the third line, list the actual count of each.

(3) Fire mission data.

(a) Record fire command elements in this portion unless they are already standardized.

(b) Record resupply and transfer of ammunition.

(4) AMMUNITION EXPENDED

(a) In this column, record all ammunition expended or received.

(b) Circle each round shot in a fire mission, and record the cumulative count. Upon receipt of EOM, subtract total rounds fired (the last circled number in the column) from the initial or latest total.

(c) Entries for resupply and transfer of ammunition are not circled.

c. The DA Form 4513 or 4513-R should be turned in (usually to the GSG, platoon sergeant, or platoon leader) once every 24 hours for the purpose of updating the DA Form 2408-4. The unit SOP applies. The PAGE OF block is completed at this time. The form should be filled out completely to eliminate errors. The chief of section should check it periodically for neatness and accuracy

Note: A cumulative count is kept to reduce errors in deriving totals. Once totals are derived, except those listed in the AMMUNITION/FUZES ON HAND block, they are represented by two slashes in the upper left-hand corner of the block being totaled. When a page is filled out in full, the totals placed in the AMMUNITION/FUZES ON HAND block on the next page are the last listed totals. At the end of a mission or upon resupply, the amounts of ammunition on hand are totaled on the appropriate line. Thus, a running count is continually maintained.
