River Division 594 (RIVDIV-594)
U.S. Army
River Division 594 (RIVDIV-594) was a unit of the U.S. Navy’s Mobile Riverine Force during the Vietnam War, activated in the late 1960s as part of Task Force 117. Equipped primarily with Patrol Boat, River (PBR) craft, the division conducted patrols, interdiction, and combat operations along the Mekong Delta’s intricate waterways to disrupt Viet Cong supply lines and provide support to ground forces. RIVDIV-594’s missions included search-and-destroy operations, convoy escort, and insertion/extraction of Army units in contested areas. The division played a crucial role in riverine warfare, contributing to joint Army-Navy operations before being deactivated as U.S. forces withdrew from Vietnam.
