This is a category of Armored Personnel Carriers in the Battlefield Series.
An Armored Personnel Carrier (APC) is a ground transport vehicle. It can protect its passengers from small arms fire, and may be able to withstand attacks from heavier weapons depending on the design. APCs may carry mounted weapons designed to repel enemy infantry. As it does not possess weaponry capable of engaging enemy armor, APCs typically retreat after deploying their payloads.
(An IFV is a similar vehicle capable of combating enemy armor.)
