Marines from the Amphibious Combat Vehicle new equipment training team take the vehicle out for a spin at the Amphibious Vehicle Test Branch facility aboard Camp Pendleton, Calif. Marines train to become subject matter experts on new equipment, such as the ACV, in order to teach other Marines how to maintain and operate newly-fielded equipment. In addition to instructing Marines, the NET team reviews and provides input to training manuals and standard operating procedures, help develop ranges and plan field operations for Marines.
