The S250 communications shelter, which is used in conjunction with the

M1037, is a container that is mounted on the back of the vehicle.

The

container, when received, is empty; however, it provides the attachments to

incorporate radio communications equipment, depending on the needs of the

unit, and on the equipment that the unit is authorized to use.

This is

usually found configured as a radio teletypewriter (RATT) and is normally

found in the battalion area. This equipment permits the battalion commander

to communicate, by voice, with his subordinate units and also to higher

headquarters.

A fully loaded M1937 shelter carrier will climb road grades as steep as 600.

Like its counterparts previously discussed, the carrier is capable of

fording hard bottom water crossings of 30 inches without the deep water

fording kit being installed. If the kit is installed, the vehicle can ford

water up to 60 inches. Fully loaded, the M1037 has a maximum cruising range

of 300 miles.

(3) Combat Service Support. In the combat service support role, the

HMMWV is used as either an ambulance or a logistics support vehicle. In the

ambulance mode there are three vehicles used. The M996, capable of carrying

two litter patients, and the M997 which is like the M996 except that it is

expanded to hold two additional litter patients. These two vehicles provide

armored protection for the crew and patients. The M996 can be transported

by a CH47 Chinook helicopter, while the M997 cannot be. The third version

is the M1035, two litter, soft top ambulance. The M1035 is the same as the

M996, except that it has no armor protection for the crew and patients.

The M998 and the M1038 are the two logistics support versions of the HMMWV.

The M998 and M1038 cargo/troop carriers are used to transport equipment,

materials, and/or personnel. The cargo carrier is capable of transporting a

payload (including crew) of 2500 pounds.

The troop carrier is capable of

transporting a two man crew and eight passengers. The cargo/troop carrier

has a four-man crew configuration.

Each uses a troop seat kit for troop

transport operations.

The M1038 is equipped with a winch that permits

recovery operations of similar vehicles.

Fully loaded, the M998 and the

M1038 cargo/troop carriers are capable of climbing road grades of 60.

Again, like the previously
