c. Battalion Aid Station. Ground ambulances (usually M113s in heavy
divisions) from the battalion aid station (BAS) collect casualties from the CCP's and
transport the casualties to the battalion aid station. At the BAS, the casualties are treated
by members of the treatment squad. Casualties requiring additional medical treatment
(not returned to duty) are evacuated to the forward support medical company (FSMC) or
forward surgical team (FST).
d. Ambulance Exchange Point. The forward support medical company (FSMC)
is responsible for evacuating casualties who are not returned to duty from the BAS's.
Sometimes, both tracked (M113) and wheeled ambulances are used. The tracked
ambulance evacuates casualties from the aid station and takes them to an ambulance
exchange point (AXP). At the AXP, the casualties are transferred to a wheeled
ambulance from the forward support medical company that completes the trip to the
forward support medical company.
e. Forward Support Medical Company. Casualties are evacuated from the
BAS's by ground and/or air ambulances from the FSMC. Casualties who cannot be
treated by the FSMC and returned to duty are evacuated by air and/or ground
ambulances to division medical treatment facilities or combat support hospitals in the
theater of operations.
f. Main Support Medical Company. Casualties are evacuated from the FSMC's
by ground and/or air ambulances from the division MTF. Casualties who cannot be
treated by the division medical facility and returned to duty are evacuated by air and/or
ground ambulances to an appropriate MTF in the Corps support area.
g. Corps Medical Treatment Facilities. Corps level MTF's evacuate casualties
from the division MTFs. Corps level facilities include the mobile Army surgical hospital
(MASH), the combat support hospital (CSH), and the evacuation (Evac) hospital.
Casualties that cannot be treated by corps level facilities and returned to duty are
zone level MTF's evacuate casualties from corps MTF's. The primary MTF of the
COMMZ is the general hospital. Field hospitals and station hospitals are also located in
The station hospital may eventually be eliminated.
i. Zone of the Interior Medical Treatment Facilities. Casualties who require
further medical treatment or who will not be returned to duty are evacuated from the
general hospital in the COMMZ to a MTF in the zone of the interior (ZI). This is usually
a military hospital [medical center (MEDCEN) or Army medical department activity
(MEDDAC)], other federal hospital, or CMCHS (civilian/military contingency
hospitalization system) hospital inside the United States (CONUS).
