River Squadron Five

River Squadron Five was a U.S. Navy unit established during the Vietnam War as part of the Mobile Riverine Force. Activated in 1967, the squadron’s primary mission was to patrol and secure the Mekong Delta’s complex waterways, supporting ground operations and interdicting Viet Cong supply lines. River Squadron Five operated a variety of riverine craft, including Patrol Boat, River (PBR) and Armored Troop Carriers (ATC), often engaging in intense combat with enemy forces. The unit played a crucial role in joint Army-Navy operations and was instrumental in maintaining control over vital river routes until its deactivation in 1970.
