COMMAND AND RECONNAISSANCE VEHICLES

The command and reconnaissance vehicle developed by FMC, the so-called M113 1/2

After the was retired from service, the M113 was modified to provide an interim armored cavalry reconnaissance vehicle. One such modification evaluated at Fort Knox during 1975 was the armored cavalry cannon vehicle (ACCV). This was an M113A1 fitted with the M27 weapon station formerly used on the M114A1E1. On this weapon station, the 20mm gun M139 could be aimed and fired without opening the cupola and exposing the gunner.

In early 1963, FMC had presented a new armored command and reconnaissance vehicle based upon the components of the highly successful M113 armored personnel carrier. The initial design offered the choice of either the gasoline or diesel engine. However, the vehicle was developed using the diesel power package from the M113A1 armoredpersonnel carrier.

Sometimes referred to as theM113Al 1/2, the command and reconnaissance vehicle was smaller than the and it was manned by a crew of three. The driver and observer were in the front hull on the left and right respectively. The commander's station was in the center of the vehicle. On the early pilot, this was a mock-up of the Model X commander's cupola fitted with a dummy 20mm gun.

Each crew member had a hatch above his station. The driver and observer each had four Ml7 periscopes in the hull roof around their hatch. The driver's hatch cover was fitted for the installation of an M19 infrared periscope. With the M26 cupola, the commander had eight vision blocks for a 360 degree view. An access door was in the right side of the hull adjacent to the commander's station.

The command and reconnaissance vehicle was assembled by welding aluminum alloy armor plate with a thickness of 1/4 inches on the top, sides, rear, and upper front. The lower front and the floor were 13/4 inches and 1 inch thick respectively. The vehicle was amphibious without any special preparation. A trim vane was installed on the front hull and folding water shields or snorkels were fitted around the intake and exhaust grilles on the hull roof.

On this little, rear engine, front drive vehicle, the General Motors 6Y53 diesel engine and the Allison TX-100 transmission were installed in the rear hull. Power was transmitted by a propeller shaft to the DS200 controlled differential in the front and then through the final drives to the sprockets for each track. The vehicle rode on the same 15 inch wide T130E1 tracks as the .

The flat track, torsion bar, suspension had four road wheels per side. An adjustable idler was at the rear of each track. The command and reconnaissance vehicle had an overall width of only 95 inches. As a result, the torsion bars were shorter than those on the M113 suspension. When completed, the armament was a .50 caliber machine gun in an M26 cupola mount for the vehicle commander.

This could be replaced by the M27 cupola mount with the 20mm gun Ml39, the Model 74 cupola with two 7.62mm M73 machine guns, the Model 100-E cupola with a single 7.62mm machine gun, or the .50 on the external mount used on the М113 armored personnel carrier.

Experimental mounts also were proposed for weapons up to 25mm which could be loaded, aimed, and fired from within the vehicle. Another option was the installation of a 7.62mm M60 machine gun on an external mount in front of the observer's hatch. Other remote control 20mm gun mounts were proposed for the commander's station as well as Entac or TOW missile installations.

Combat loaded, the command and reconnaissance vehicle weighed 18,650 pounds. The maximum speed was 40 miles per hour on roads and 4.1 miles per hour in water. The cruising range on roads was approximately 325 miles. The blunt front hull exposed the tracks allowing the vehicle to climb steep banks and easily exit from most waterways.
