serial at some point. The AATF commander must be prepared to effect the bump plan if
the aircraft carrying casualties do not return to the PZ for the next lift.

(c) Confusion. A casualty collection point should be selected so that it does not interfere
with the air assault that is still in progress. Aircraft arriving at the PZ full of casualties may
cause confusion on the PZ as troops are trying to load, and casualties are being unloaded
from the aircraft.
(d) Aircraft rejoin. A site should be selected that allows the lifting helicopters to quickly
drop off the casualty and return to the PZ to continue the tempo of the air assault
operation.
6-6. CASUALTY EVACUATION MISSION PLANNING CONSIDERATIONS
CASEVAC mission planning must be detailed. The air movement planning considerations listed in Chapter 4
apply to CASEVAC operations as well. Units conducting CASEVAC missions should refer to this chapter to
thoroughly plan and accomplish the mission. In addition, the following mission planning considerations
should also be considered when preparing to conduct a CASEVAC mission:
a. Landing Zones/Pickup Zones. LZs /PZs for CASEVAC operations are the responsibility of the
supported unit. For example, battalion aid stations are responsible for setting up the LZ/PZ for
CASEVAC operations. LZ/PZ selection criteria for a CASEVAC LZ/PZ are location, marking,
communications, capacity, and obstacles.
(1) Location. The LZ/PZ must be in close proximity to the aid station. Casualties may have to be
carried by hand to the waiting aircraft. However, the LZ/PZ must be set up at a distance where it
will not interfere with aid station operations. If possible, set the LZ/PZ up downwind from the
aid station. This will help prevent blowing dust on the aid station. A minimum distance of 150
meters should be acceptable to keep aircraft from interfering with aid station operations.
(2) Marking. LZ/PZ markings must be visible from the air. During the day, marking of the
LZ/PZ can be accomplished using a VS-17 panel, smoke, or signal mirror. If using a VS-17
panel, ensure it is visible from the air. At night, an inverted Y is used to designate the aircraft
touchdown point. However, this may not be visible from the air. LZs/PZs should also have a far
recognition signal, such as a swinging chem light or strobe light, to make the LZ/PZ easier to
find.
(3) Communications. Air-to-ground communications should be maintained between the aircraft
and the LZ/PZ. Effective communications will make movement times faster and assist the
aircraft in locating the LZ/PZ.
(4) Capacity. LZ/PZ selection is based on the number of aircraft and type aircraft that will be
used for the CASEVAC operation. The size determines how many aircraft can be landed at one
time to load casualties.
(5) Obstacles. LZs/PZs should be free of obstacles. Obstacles such as cables, wires, antennas,
large rocks, excessive slope, and large ruts can make the location unsuitable. Obstacles that
cannot be cleared from the location should be marked. If communications are maintained with
the aircrew, advisories should be provided to the crews as to hazards in the LZ/PZ.
b. Medical Support. As defined, CASEVAC operations do not provide any en route medical treatment.
Commanders and medical personnel must consider this when determining if utility helicopters should
be used to transport casualties.
c. Litters. Flight crews conducting CASEVAC missions must be told what to do with litters. The
FM 1-113 Chapter 6
6-6
battalion aid stations need to have litters resupplied as casualties are evacuated to a higher level of care.
Aircraft on CASEVAC missions may need to pick up litters at the drop off location and return them to
the casualty PZ to keep the battalions resupplied. For example, once helicopters move casualties from a
battalion aid station (MAS or FAS) to the BSA, the MAS or FAS may need the aircraft to backhaul
litters for use in further CASEVAC missions. Flight crews must be briefed of this requirement and be
prepared to execute litter backhaul to keep the battalion aid stations supplied with necessary litters.
d. Army Airspace Command and Control. If the division has MEDEVAC aircraft attached or OPCON
to it, the DMOC will be responsible for planning the A2C2 measures that these aircraft will be using.
Utility helicopters conducting CASEVAC missions in support of the medical companies of the BSA or
DSA should check with the DMOC for the current MEDEVAC airspace structure. These procedures
will also be specified in the airspace control order or SPINS.
