M1123 Heavy HMMWV Cargo/Troop Carrier

The M1123 heavy cargo/troop carriers, similar to the M1097A2 heavy HMMWV variant, were used to transport equipment, materials, and/or personnel. The M1123 troop carrier was capable of transporting a 2-man crew and 8 passengers. Available in 2- and 4-person configurations, this model could accept installation of troop seats and other modifications. The heavy variant cargo carrier is capable of transporting a payload (including crew) of 4,400 pounds (1,998 kilograms).

The M1123 used 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 M1123s were 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. Fully-loaded M1123 heavy variant cargo/troop carriers could climb road grades as steep as 60 percent (31 degrees) and traverse a side slope of up to 40 percent (22 degrees). The vehicle could ford hard bottom water crossing up to 30 inches (76 centimeters) without a deep water fording kit and 60 inches (152 centimeters) with the kit.

The M1123 models, like the M1097A2 and other A2 models, had new bumpers, along with the other A2 improvements, which made the vehicles slightly longer. A 9,000 lb winch was also available for the M1123 as an option. These differences affected approach angle, special winch-assisted Operations, vehicle length, vehicle weight, and shipping dimensions. It did not affect the basic purpose, performance, or special limitations of the vehicles. The M1123 troop/cargo variant was intended to replace the M998, M998A1, M1038 and the M1038A1 variants.
