1-10. HEAVY VARIANT CARGO/TROOP CARRIERS
(M1097, M1097A1, M1097A2, AND M1123)
a. Differences. The difference between the M998 and M998A1 cargo/troop
carriers and the M1097, M1097A1, M1097A2, and M1123 heavy variant cargo/troop
carriers is that the M1097, M1097A1, M1097A2, and M1123 are specifically
designed to accommodate a higher payload capacity. The M1123 and A2 models
have new bumpers, which make the vehicles slightly longer. A 9,000 lb winch is
also available for the M1123 and A2 models as an option. These differences affect:
• Approach Angle
• Special Winch-Assisted Operations
• Vehicle Length
• Vehicle Weight
• Shipping Dimensions
It does not affect the basic purpose, performance, or special limitations of the vehicles.
b. Purpose of the Vehicle. M1097, M1097A1, M1097A2, and M1123 heavy
variant cargo/troop carriers are used to transport equipment, materials, and/or
personnel. The heavy variant troop carrier is capable of transporting a two-man
crew and eight passengers. The heavy variant cargo carrier is capable of
transporting a payload (including crew) of 4,400 pounds (1,998 kilograms). The
M1097, M1097A1, M1097A2, and M1123 use a troop seat kit for troop transport
operations, a 200 ampere umbilical power cable to power shelter equipment, and
stowage racks for ammunition and equipment. For higher payload capacity, the
M1097, M1097A1, M1097A2, and M1123 are equipped with a reinforced frame,
crossmembers, lifting shackles, heavy-duty rear springs, shock absorbers,
reinforced control arms, heavy-duty tires and rims, and a transfer case and
differential with a modified gear ratio.
c. Performance. Fully-loaded M1097, M1097A1, M1097A2, and M1123
heavy variant cargo/troop carriers will climb road grades as steep as 60% (31°) and
traverse a side slope of up to 40% (22°). The vehicle fords hard bottom water
crossing up to 30 inches (76 centimeters) without a deep water fording kit and
60 inches (152 centimeters) with the kit. Refer to table 1-15 for cruising range.
