About this Unit
The Brownwater Navy was a specialized branch of the United States Navy formed during the Vietnam War to conduct operations in the shallow rivers, canals, and coastal waters of South Vietnam. Officially known as the United States Navy's "Riverine Forces," these units used small, heavily armed boats such as Patrol Boat, River (PBR), Swift Boats (PCF), and Armored Troop Carriers (ATCs) to provide mobility, firepower, and logistical support to U.S. Army and South Vietnamese forces. Brownwater Navy sailors faced constant ambushes, mines, and hostile fire while patrolling the Mekong Delta and other waterways. Their crucial efforts disrupted enemy supply lines, supported ground operations, and played a significant role in counterinsurgency missions throughout the conflict.
