USMMAV

The United States Merchant Marine Armed Vessels (USMMAV) refers to the fleet of civilian merchant ships that were armed and operated under U.S. government authority during times of war, most notably during World War II. These vessels, manned by civilian mariners and often escorted or supervised by Navy Armed Guard detachments, played a critical role in transporting troops, supplies, and equipment to various theaters of operation. Despite not being formal combatants, USMMAV crews faced significant danger from enemy submarines, aircraft, and surface raiders, suffering heavy casualties throughout the conflict. Their bravery and contribution were crucial in sustaining Allied operations, earning them recognition as an essential component of America's wartime logistics.
