The M114 Command and Reconnaissance Carrier is a Vietnam War-era tracked armored fighting vehicle, used by the United States Army.

However, unlike the M113 which became one of the most successful armoured vehicles, it quickly proved unsuited to use in the Vietnam War, and was replaced in the reconnaissance role by the M551 Sheridan light tank.

The M114 was 4 inches lower than the M113, and its upper forward glacis plate had a shallower angle than on the M113, resulting in a somewhat sleeker profile.

The updated M114A1 allowed the firing of the machine gun from the inside, utilizing manual traverse and elevating mechanisms.

[4] During combat operations in Vietnam, the M114 armored reconnaissance vehicle proved to be mechanically unreliable, underpowered, had extreme difficulty conducting cross country operations,[5] and its lack of resistance to land mines was fatal; a mine that would nearly destroy a standard M113 ACAV would literally blast an M114 reconnaissance vehicle in half.

The 3rd Armored Cavalry Regiment at Fort Bliss, TX was reportedly the last U.S. Army unit to replace their M114s with M113s in late 1979 or early 1980.
