The ACV TTU is composed of a cadre of experienced assault amphibian Marines working to create a standardized program to certify Marines to operate and maintain ACVs. As part of a Headquarters Marine Corps initiative, once operational, the ACV TTU will certify ACV crewmembers, vehicle commanders, maintainers, and unit leadership on the safe operation, maintenance, supervision, and employment of the ACV.
