The attack on USNS Card was a Viet Cong (VC) operation during the Vietnam War. It took place in the port of Saigon in the early hours of May 2, 1964, and was mounted by commandos from the 65th Special Operations Group (Vietnamese: Đội Biệt động 65). Card was first commissioned into the United States Navy during World War II. Decommissioned in 1946, Card was reactivated in 1958 and reentered service with the Military Sea Transport Service, transporting military equipment to South Vietnam as part of the United States military commitment to that country.
