New Amphibious Combat Vehicle "ACV" - U.S. Marines and Navy 

U.S. Marines and the US Navy test the new amphibious combat vehicle "ACV", with the amphibious transport dock ship USS Somerset (LPD 25), to assess and verify the Amphibious Combat Vehicle's ability to integrate with naval shipping as part of the vehicle’s developmental testing off the shore of Marine Corps Base Camp Pendleton, California.
The Marines of AVTB are currently testing the Marine Corps’ newest amphibious vehicle, which will replace the Amphibious Assault Vehicle. This was the first time Marines have operated the new vehicle while boarding and departing a ship.
