Riv Div 572

River Division 572 (Riv Div 572) was a unit of the United States Navy's Mobile Riverine Force during the Vietnam War. Formed as part of the "Brown Water Navy," Riv Div 572 operated Patrol Boat, River (PBR) craft, primarily conducting patrols, interdiction missions, and troop transport along the Mekong Delta's complex waterways. The division was tasked with disrupting Viet Cong supply lines, providing fire support, and ensuring riverine security for allied forces. Riv Div 572 distinguished itself through its adaptability and effectiveness in the challenging riverine environment until the gradual drawdown of U.S. Navy forces in Vietnam.
