THIS CHAPTER IMPLEMENTS STANAGs 2863, 3117, AND 3570. |
Pathfinders conduct many different
missions, many of which are additional requirements of the ground
units' operation.
Pathfinder missions must be planned
in detail to ensure success of the ground units' mission. The
amount of detail is dictated by the amount of time allotted to
plan.
Upon notification of a pending
operation, the senior pathfinder gives a mission alert as early
as possible and follows it with a warning order. The warning order
includes sufficient information to permit initial preparations
for the operation. It should include:
-
A
roll call.
-
A
brief statement of the enemy and friendly situations.
-
The
mission.
-
The
chain of command and task organization.
-
The
individual uniform and equipment (if not in the SOP).
-
The
required equipment.
-
The
time schedule to complete work priorities; includes place, time,
and personnel required.
-
Specific
instructions and personnel attached.
-
Time
coordination.
Inspection of personnel and equipment
begins upon receipt of the alert or the warning order. Personnel
or equipment augmentation, if required, is also accomplished at
this time.
a. Equipment is normally prepared
in the following priority:
-
Radios.
-
Navigation
aids, both electronic and visual.
-
Weapons
and essential individual equipment.
-
Assembly
aids.
-
Miscellaneous
items.
c. As more information is received,
personnel and equipment are reorganized to better accomplish the
mission. Time permitting, rehearsals are conducted using available
briefing aids and terrain that most nearly resembles the operational
area.
d. Security is mandatory for thesuccess of an operation; therefore, personnel are given only the
minimum essential information needed to complete each phase of
an operation. Individuals who have received detailed information
are isolated (for security). Operational situations dictate security
requirements.
Ground and aviation commanders
coordinate and plan the details of operations that require pathfinder
assistance. The pathfinders may be required to recommend the exact
location of DZS or LZs, the time schedule, the landing formations,
and the techniques to be employed. These recommendations are likely
for any type of operation (combat assault, reinforcement, artillery
displacement, resupply, or evacuation). The DZ or LZ is selected
by the supported unit commander after considering the factors
of METT-T, and the advice of the pathfinder and aviation commanders
or their representatives.
a. While preparing for an operation,
aviation liaison officers and ground unit commanders coordinate
factors used to formulate an air movement table with the pathfinders.
Their responsibilities include:
-
(1) Operational location (coordinates).
(ALO & GUC)
(2) Location of the communications
checkpoint and alternate communication checkpoint (coordinates).
(ALO)
(3) Location of release point
(coordinates and whether manned or unmanned). (ALO)
(4) Time the site is to be operational.
(ALO & GUC)
(5) Aircraft information (formation,
time interval, number of flights, drop speed, and drop altitude).
(ALO)
(6) Pathfinder transportation
and time available for briefing. (ALO)
(7) Pathfinder transportation
station time. (ALO)
(8) Routes into the objective
area. (ALO & GUC)
(9) Call signs (aircraft, pathfinders,
supported units, other friendly units). (ALO & GUC)
(10) Primary and alternate frequencies
(aircraft, pathfinders, supported units, other friendly units,
homing beacon). (ALO & GUC)
(11) Fire support (artillery,
tactical air support). (ALO & GUC)
(12) Weather forecast (ceiling,
visibility, temperatures [high, low]). (ALO)
(13) Logistical support (locations
of medical aid station, prisoner collection point, fuel, ammunition,
rations). (ALO & GUC)
(14) Alternate plan (evacuation
plan, escape and evasion). (ALO & (ALO & GUC)
(15) Friendly unit locations.
(ALO & GUC)
(16) Authority to implement mission
change. (ALO & GUC)
(17) Support personnel required.
(GUC)
(18) No-land or no-drop signals.
(ALO)
(19)Markings for obstacles. (Done
only on request of flight commander.)
(20) Marking objective site for
identification from the air. (ALO
(21) Time allowed for approval.
(ALO & GUC)
c. When the pathfinder gets to
the objective site, he may decide that it is not suitable, as
regards the coordinated landing formation, heading, drop altitude,
or the ground site itself. He then coordinates with the ground
and or aviation commander(s) if any of the original requirements
are to be amended. Depending upon the situation (METT-T), the
commander(s) determines what, if any, changes may be made to accomplish
the mission. The pathfinder can also coordinate for authority
to change requirements if contact with the GUC or aviation commander
is not possible or practical.
d. Based upon coordinated plans
for an operation, the pathfinder requests augmentation in personnel
and equipment. He considers the following:
-
Mission.
-
Use of personnel and equipment
for security.
-
Requirement to assist in the assembly
of personnel, supplies, and equipment of supported units.
-
Need for assistance in removing
obstacles.
-
NBC survey or monitoring requirements.
-
Assistance
required for transporting and operating navigational aids under
pathfinder direction.
2-4. LINKUP WITH SUPPORTED UNIT
Pathfinders join the supported
unit in sufficient time to allow final coordination between pathfinder,
aviation, and lifted ground unit representatives. However, if
pathfinders enter an LZ or DZ ahead of the assault echelon, and
have been designated to accompany and provide continuous support
to a ground unit, then the linkup with the supported unit normally
occurs after the initial phase of the air movement.
The pathfinder leader issues his
operation order. If he issued it prior to linkup with the supported
unit, he should issue any changes as a fragmentary order. If the
unit SOP does not describe each member's duties, the order must
do so. Team members are given an opportunity to study maps, aerial
photos, and terrain models of the area. The order must contain
detailed information on the location and the operation of proposed
air delivery facilities, flight routes, flight formations, time
schedules, RPs, and CCPs. a. A final, detailed check is made of
the equipment to be used in the operation. A decision is made
on the exact manner in which the equipment is to be transported
into the objective area. All items of equipment are prepared for
rapid displacement. b. A final weather and operation briefing
is held for the pathfinders just before departure. Final coordination
between the pathfinders and supported units is accomplished at
this time.
Pathfinders are organized to meet
specific requirements of the mission. In most operations, three
to six men makeup the average size pathfinder element
at an LZ or DZ or when
in continuous support of an infantry battalion. A pathfinder section
is seldom employed
as a unit at a single location. The pathfinder leader plans for
widely separated and disconnected operations by his elements.
Pathfinders can be inserted into
an area by a variety of air, sea, or land transportation.
a. Landing by Helicopter. More
personnel and equipment can be delivered in a better state of
operational readiness when landed by helicopter. This delivery
is more precise and more flexible than parachute delivery and
can be carried out in marginal weather. In some areas, terrain
may preclude helicopter landings. Trained personnel can rappel
from helicopters hovering over unsuitable landing areas. The use
of troop ladders from hovering helicopters also allows personnel
to be inserted or withdrawn from such areas. Helicopters can also--
-
(1) Furnish a means of aerial
radiological monitoring.
(2) Rapidly shift or evacuate
pathfinders.
(3) Enable nonparachutists to
accompany pathfinders in a supporting role.
(4) Be a delivery means when rain
or low ceilings prohibit parachuting.
-
(1) Depending upon wind conditions,
pathfinders should compute their desired parachute RPs before
arrival over the DZ. For accuracy and security, parachute jumps
are made at the lowest practical altitude. Jump altitudes and
procedures for personnel are prescribed in SOPs for the types
of aircraft involved and vary in accordance with peacetime and
wartime restrictions (FM 57-230).
(2) Pathfinders are highly trained
parachutists who can be inserted into unimproved and marginal
DZs. Their training in emergency landing procedures, canopy control
of the maneuverable parachute, and expertise in rough terrain
DZs provides flexibility when planning parachute delivery.
(3) When parachuting, pathfinders
carry essential operational items of equipment. This gives them
immediate access to needed equipment upon landing. Special care
is taken by padding and carefully arranging items into equipment
containers during the preparation phase.
(4) Parachute entry has its greatest
application during nonilluminated, nonsupported night operations
when secrecy is the primary consideration.
(5) The need for comparatively
large, secure, and obstacle-free landing areas, however, limits
the landing of freed-wing airplanes for pathfinder delivery.
Infiltration by land is generally
the least desirable means of pathfinder delivery. It is usually
limited to short movements by small elements. Land infiltration
is used when visibility is limited over difficult terrain, whenthe enemy's lines are overextended, when the combat zone is fluid,
or when portions of enemy boundaries are not secured. Conversely,
a well-organized, stable, and close-knit enemy defense in depth
may prohibit land infiltration. When time is available, overland
movement to an objective may be used in conjunction with parachute
or airlanded infiltration to increase security of an operation.
This involves positioning pathfinder
elements within an operational area while a friendly force withdraws
from the area. Stay-behind operations may be considered when the
enemy has the capability of overrunning friendly areas and an
air assault attack has been planned to reoccupy the area, or as
a deceptive measure to lure enemy forces into a vulnerable position.
In addition to providing air traffic
advisories and navigation assistance for airplanes and helicopters,
pathfinders can perform limited physical improvement and NBC monitoring
and surveying within LZs or DZs. Their support is dictated by
the availability of pathfinders, the tactical plan, the complexity
of the operation, the terrain, and the air assault proficiency
of the supported ground unit. In any air assault operation, however,
positive aircraft control is essential. During an air-assault
operation, pathfinders should be cross-loaded when accompanying
the initial assault elements into an LZ.
During daylight air assaults,
pathfinders should accompany designated pathfinder aircraft or
the initial assault elements into an LZ. Air traffic control and
other pathfinder assistance is then provided to all subsequent
lifts of troops, supplies, and equipment. If pathfinders precede
assault elements, the time may vary from a few minutes to several
hours, depending upon the situation. The tactical plan, to include
strikes in and around the LZ (by artillery, USAF aircraft, or
armed helicopters), dictates this time, or precludes the early
entry of pathfinders altogether.
In daylight operations, pathfinders
are not inserted into an LZ before the initial assault echelon
unless the LZ requires extensive improvement or unless unusual
control problems are anticipated.
The method of delivering pathfinders
at night is determined by security and operational requirements.
Pathfinders may move cross-country on foot, airdrop onto or near
objective areas, airland in total blackout, or airland with minimum
natural illumination. During such operations, pathfinders may
be delivered ahead of the main body to reconnoiter the LZ, install
visual and electronic aids, and establish air traffic control.
Personnel from the supported ground unit may accompany pathfinders
to provide security and to assist in clearing obstacles. The on-site
pathfinder element remains concealed and observes the objective.
Pathfinder analysis of the situation includes the planned landing
formation, heading, and assembly area. To avoid mission compromise,
movement on the DZ/LZ is avoided until the incoming aircraft reach
the CCP.
As the size of the ground force
decreases at an LZ, vulnerability to attack increases. Therefore,
employ pathfinders to expedite air assault extraction (withdrawal
or pickup) operations.
a. Planned artillery fires/air
strikes, as well as the maintenance of ground security to the
last possible moment, make it essential that positive control
of supporting aircraft be maintained throughout the extraction
operation. Aircraft are carefully controlled to ensure they land
at specific points within the extraction site (covered by ground
security). This enhances the expedition and safe withdrawal of
personnel, equipment, and aircraft from the area.
b. If not already on the ground
with the lifted unit, pathfinders must arrive at the extraction
site in time to reconnoiter the area thoroughly and coordinate
with the lifted unit.
c. During the planning stage,
near and far rally points are designated for use if the LZ or
DZ becomes untenable. Pathfinders may have to fight their way
to these rally points and reorganize. Far rally points, several
kilometers from the LZ or DZ, are designated to facilitate survival,
evasion, resistance, and escape operations.
Pathfinders can be employed in
staging areas to provide air traffic advisories in the absence
of ATC units. They may also act as liaison between the aviation
and ground units and assist the ground unit commander in the preparation
and positioning of troops, supplies, and equipment for air movement.
When a temporary staging area is established to support an operation
of short duration, pathfinders should be in the staging area before
the operation begins to ensure adequate reconnaissance, marking,
coordination, and establishment of positive ATC. Positive ATC
in staging areas is essential to safe, efficient, and expeditious
movement of helicopters or airplanes. The need for positive ATC
increases when the weather deteriorates, when the number of aircraft
increases, or when changes in the situation or plans require it.
Pathfinders should be employed
to assist the rapid and safe displacement of artillery, day or
night. Coordination with ground and aviation unit commanders and
an understanding of their SOPs ensures accurate and efficient
delivery of equipment, personnel, and ammunition.
2-14. SUPPORT OF GROUND OPERATIONS
Pathfinders may provide continuous
assistance and control of aircraft during ground operations requiring
sustained Army aviation support. Pathfinders attached to infantry
battalions may be further attached to companies to provide support
consistent with availability of personnel and equipment. Continuous
support improves operational efficiency and aviation safety during
all types of air assault operations; however, it cannot be continuously
provided by aviation units that have only limited pathfinder resources.
In such cases, pathfinders are normally employed on a short-term,
priority basis wherever they can assist in the accomplishment
of major unit missions. In the absence of pathfinders, selected
personnel within ground units are trained and prepared to provide
minimum assistance to supporting aircraft.
By joint US Army and USAF agreement,
Army pathfinders may provide day or night control for USAF aircraft
on airfields, DZs, and LZs in the absence of USAF CCTs. However,
it may be necessary to provide pathfinders with UHF and VHF communications
equipment compatible with that of USAF aircraft.
Situations may require the simultaneous
control of mixed air traffic at the same location, such as resupply
parachute drops into forward helicopter LZs. As a rule, helicopter
traffic can be expected at all fried-wing airfields. Mixed air
traffic often presents difficult control problems; strict control
measures must be applied. Landing, parking, loading, unloading,
refueling, and rearming areas are designated, coordinated, and
clearly identified to ensure control.
An essential element of a successful
pathfinder operation is communication by GTA voice radio. This
is the first item placed in operation at an LZ or DZ, and it should
be the last item taken out of operation.
a. Pathfinders must have a thorough
understanding of radio procedures to include phraseology unique
to ATC (Chapter 3). Communications must be clear, concise, applicable,
accurate, and correctly timed. To achieve speed and clarity of
transmission, radio discipline is practiced by pathfinders and
aviators. Unnecessary messages are not transmitted. Pathfinder
ATC frequencies (Figure 2-1) should only be used for ATC, except
in emergencies.
b. Because of the amount of vital
information exchanged, aircraft crews normally record the important
portions of GTA messages to ensure that instructions are understood
and followed.
c. Pathfinders use electronic
homing beacons, visual aids, and arm-and-hand signals to complement
voice communications. Pilots and transported troops must understand
the purpose and meaning of the aids displayed and the techniques
employed (STANAG 3570). (Arm-and-hand signals and visual aids
are discussed in FM 21-60.)
d. Whenever possible, pathfinders
monitor supported unit command radio nets to keep abreast of changing
situations that could influence pathfinder operations. e. Positive
communications are established between pathfinder ATC facilities
and collocated fire support elements. This ensures that timely
and accurate information concerning friendly fires is available
to aircraft. f. The constant use of radios in pathfinder operations
gives the enemy frequent opportunities for intercepting, analyzing,
and exploiting friendly transmissions to gain intelligence and
conduct electronic jamming and deception. Defeating enemy jamming
or imitative deception lies largely with the radio operator. He
must be proficient in recognizing and reporting this deliberate
interference and combating it by employing electronic counter-countermeasures.
Provisions for defense against electronic countermeasures, including
transmission security and the use of alternate means of communication,
are part of the planning and execution of tactical missions.
2-18. TERMINAL GUIDANCE BY SUPPORTED
UNITS
Terminal guidance is information
and minimal guidance provided to pilots by other than qualified
pathfinders within a ground unit. It is normally furnished by
selected personnel within the supported unit using organic and
improvised equipment.
a. Terminal guidance personnel
should be familiar with the supporting aviation unit SOP and should
be able--
-
(1) To operate electronic and
visual navigation aids to assist aircraft in locating LZs and
DZs.
(2) To provide essential information
through GTA radio to guide and control Army aircraft.
(3) To reconnoiter and recommend
suitable LZs and DZs.
(4) To determine, recommend, or
accomplish ground-clearing pioneer work to prepare LZs and DZs.
Threat comes in many forms, and
all must be considered to ensure mission success. Anything that
may disrupt, delay, or cause mission failure is considered a threat.
Voice control of aircraft by pathfinders
is limited, thus close coordination between the ground unit commander
and the air mission commander is important. Navigation presents
special problems because of the low altitudes that aviators must
maintain to avoid detection. Time, distance, routes, and tactical
instruments are critical in a high-threat environment.
a. Two pathfinders with beacons,
for example, could be placed along a route in advance of the initial
flight to provide pilots with air control points. If the pilot
needs the beacon turned on (because of error in navigation), a
prearranged signal or code word could be transmitted.
b. Or, pathfinders might discover
a threat along the primary route (such as an antiaircraft weapon);
then pilots would be alerted by prearranged code word or signal
to change to an alternate route.
2-20. TACTICAL INSTRUMENT FLIGHTS
Flights under instrument meteorological
conditions pose special problems in a high-threat environment.
This threat precludes controlled instrument flight rules (IAW
with the aviation series manuals) by forcing aircraft to fly at
altitudes well below the minimums established for normal instrument
flight.
a. Weather variances may create
a tactical emergency that requires the commander to use aviation
assets under instrument conditions well below altitudes specified
by standard instrument flight rules. Special considerations and
factors enter into a commander's decision to send aircraft on
a mission within a high-threat environment under these conditions.
Tactical instrument flight is a combat situation that meets the
following criteria:
-
(1) The mission cannot be postponed
until favorable weather.
(2) The mission will be conducted in
a high-threat environment.
(3) Low visibility en route precludes
nap-of-the-earth flight.
c. Aircraft flight altitudes are
flown in two basic modes.
(1) Mode
1. When flight altitude
is restricted by the air defense threat to altitudes below those
established by AR 95-1 (for standard instrument flight), then
a minimum clearance of 1,000 feet over mountainous terrain and
500 feet over flat terrain is possible.
(2) Mode
2. When flight altitude
is restricted to absolute minimum clearances, altitudes varying
from 50 to 500 feet above the ground, regardless of terrain, are
possible.
The enemy situation plus the terrain
and weather conditions determine what airways may be subject to
rapid relocation if the enemy can intercept aircraft using them.
Aircraft traffic management personnel (and pathfinders) can expect
to move their equipment as often as every four hours, depending
on the threat. Factors considered in establishing tactical instrument
flight airways include:
a. Threat and Terrain.Straight-line
flight between the takeoff (lift-off) point and the destination
(in both modes 1 and 2) is precluded in many instances by the
threat and terrain (Figure 2-2).
b. Flight Monitoring and LZ Approach. Enemy presence precludes pathfinder use of nondirectional beacons, and visibility must be such that pilots can proceed visually when approaching an LZ and when landing. Using radio homing signals for directional guidance is questionable. In any event, the electronic device should be oriented so that it emits its signal away from the forward edge of the battle area (if possible) to minimize detection.
