M113 ACAV (Armored Cavalry Assault Vehicle)

The Vietnam-era M113 ACAV (Armored Cavalry Assault Vehicle) version is a very important chapter in the long and proud history of the M113. Following lessons learned, in particular the loss of 14 ARVN .50 cal gunners at the Battle of Ap Bac in January 1963, the standard M113 was upgraded both in armament and armour protection to the M-113.

Two M60 GPMG's were mounted, one either side of the rear hatch, and fitted with protective gun shields. An FMC-designed armoured gun shield/turret combination was also added to the commanders cupola to afford him protection when manning the .50 cal machine gun. This vehicle was designated the M-113 Armored Cavalry vehicle (ACAV).

As a result of lessons learned, when the 11th ACR shipped to RVN their M-113's were fitted with the ew FMC gun shields and had additional M-60's mounted either side of the rear top hatch. The 11th ACR coined the term ACAV which soon became the 'official' designation of this modified M-113.
