imperative to reduce confusion. The radio nets established by the AATF will make C2 easier and contribute to the
success of the operation. Often, there are requirements to monitor more radio nets than are available in the aircraft.
Usually, no single aircraft can monitor all of the radio nets needed for an air assault. In this case, the AMC and
serial commanders will delegate responsibility for monitoring and reporting on the different nets to other aircraft
within the air assault. Figure 3-2 shows the air assault radio nets. Radio nets that will be established for the air
assault will be--
(1) Air assault task force command net. This net is an FM net (normally the command net of the lifted force
or the command net of the AATF headquarters) that is used for ground-to-ground communications during an
air assault. It is used by the AATFC to communicate with subordinate unit commanders.
(2) Combat aviation net. This is an FM radio net dedicated to air-to-ground communications between the
AMC, the AATFC, the PZCO, and the assault force commander. All aviation elements should monitor this
net. This net must be dedicated to communications between the lifted unit and the assault helicopter unit. It is
used to pass situation reports and mission changes between the assault force and the assault helicopters. It is
also used for communications between the AMC/flight leads and the PZCO. The PZCO will communicate
with the assault helicopters on this net, providing information on PZ security status, PZ hazards, and changes
to PZ operations.
(3) Air battle net. The air battle net is normally a UHF frequency for air-to-air communications. All aviation
elements (assault helicopters, air cavalry, attack) will monitor this net. The purpose of the ABN is for the
AMC to communicate with the commanders of the aviation assets involved in the air assault.

(4) Fire support net. This is an FM net operated by the AATF FSO. All aviation elements must have access
to this frequency to call for fire support. The fire support net becomes a very busy net during the air assault
operation. All of the aviation elements do not need to monitor this net, only those responsible for initiating
fire. However, all aircrews must have the frequency and call signs in case they pick up responsibility for
calling fire due to losing aircraft.
(5) Aviation internal nets. These nets are usually VHF nets and are used for internal flight communications
between serials or lifts. Use of a VHF net provides the flight or serial commanders with a dedicated
frequency with which to direct and control individual aircraft, platoons, or teams.
(6) PZ control net. This is an FM net established by the PZCO used to control the flow of personnel and
vehicles in and around the PZ. The PZCO uses this net to communicate with the PZ control elements
(security, chalks, PZ control group). This ensures that chalks are lined up in the appropriate area, external
loads are ready, the bump plan is activated if necessary, and vehicles and personnel are kept clear of PZ
operations.
(7) Assault battalion command net. This FM net will be used by the AMC or the battalion S3 to
communicate back to the aviation TOC (located in the AA). Communications on this net will be used to keep
the TOC informed of the status of the air assault and to alert the TOC of the need for support from the
aviation battalion (maintenance, fuel, back-up aircraft, CSAR).

3-7. AIR ASSAULT PLANNING STAGES
The successful execution of an air assault is based upon a careful analysis of the factors of METT-T and a detailed,
precise reverse planning sequence. The five basic plans that comprise an air assault operation are the ground tactical plan,
the landing plan, the air movement plan, the loading plan, and the staging plan. Air assaults are planned in reverse order,
beginning with the ground tactical plan and working backwards to the staging plan. Reverse planning is imperative, as
each successive planning step has an impact on the step that precedes it. The landing plan, for example, helps the air
assault planners to determine the sequence and composition of lifts during the air movement phase. Figure 3-3 shows the
reverse planning sequence.

a. Ground Tactical Plan. The foundation of a successful air assault is the ground tactical plan. All other air assault
planning stages are based on the ground tactical plan. The ground tactical plan specifies actions in the objective
area that will lead to accomplishment of the mission. The ground tactical plan addresses the following areas:
(1) Organization for combat. The mission, enemy situation, terrain, maneuver forces, and fire support assets
