The command post carrier M577A3

Incorporation of the RISE power pack and new driver's controls resulted in another change of designation. The vehicle now became the M577A3 command post carrier. In addition, the gasoline powered 4.2 kW auxiliary generator could be replaced by a 5 kW diesel driven auxiliary generator. Other improvements could include armor enhancements, the BCIS, contact spall liners, the driver's night viewer, and other modifications proposed for the armored personnel carrier. The M577A3 conversion program began in 1994.

The Ml068 standard integrated command post system (SICPS) was a modified version of the M577A2. Intended to accommodate the tactical command and control system (ATCCS), it was manned by a crew of four consisting of a commander, driver, and two command post operators. In addition to the ATCCS equipment, the Ml068 carried the 5 kW diesel auxiliary generator, a power/data distribution system, and a ten meter antenna mast.

A new extension tent with lighting was stowed on top of the vehicle. It was intended that roughly two thirds of the M577A2 fleet would be converted to the Ml068 configuration. When the Ml068 was fitted with the RISE power pack, it was designated as the M1068A3 standard integrated system.

A stretched version of the M577A3 was developed by United Defense L.P. (formerly FMC) as an independent research and development program. Referred to as the XM577A4 stretch armored tactical command and control system, it had six road wheels per side and a longer hull for increased interior space and payload capacity.

It also could be fitted with bolt-on armor as well as spall liners for additional side and roof protection. The XM577A4 stretch had an interior volume of 502 cubic feet and a payload capacity of over 5,000 pounds. It also was considered as a platform for a hazardous materials recovery vehicle and an armored medical treatment vehicle.

A modified version of the late model was proposed as a tactical operations center vehicle. With the normal silhouette of an M113, it could not be easily distinguished from the standard armored personnel carrier on the battlefield.

Manned by a crew of six, it provided stowage space for radios and map boards. The latter could be used standing in the open cargo hatch. The vehicle was fitted with external stowage racks on each side and was equipped with the external fuel tanks.

The 1975 recommendations of the Close Support Study Group resulted in the development of the fire support team vehicle (FIST-V) to provide field artillery support to armor/cavalry and mechanized infantry units. Developed by the Emerson Electric Company, it utilized many components from M901 improved TOW vehicle then in production.

The chassis was that of the equipped with the external fuel tanks. The hammer head TOW launcher was used to mount the ground/vehicle laser locator designator (G/VLLD) as well as the AN/TAS-4 night sight and the north seeking gyrocompass.

Originally designated as the XM981, it was standardized as the M981 fire support team vehicle. In appearance, it was almost identical to the M901 improved TOW vehicle. The early pilot used a different design for the hammerhead, but the production vehicles differed only slightly from the M901. When the RISE power pack was installed in the vehicle, it was designated as the M981A3.
