River Division 594 (RIVDIV-594)

• Formation and Mission: River Division 594 (RIVDIV-594) was part of the U.S. Navy’s Mobile Riverine Force (MRF) during the Vietnam War, tasked with patrolling and securing the Mekong Delta’s complex network of rivers and canals. • PBR Operations: The unit primarily operated Patrol Boat, River (PBR) craft—fast, highly maneuverable vessels designed for shallow water operations ideal for riverine warfare. • Supporting Operation Game Warden: RIVDIV-594 played a key role in Operation Game Warden, a campaign to deny Viet Cong forces access to vital waterways for supplies and movement. • High-Intensity Combat: The crews of RIVDIV-594 regularly engaged in fierce firefights with Viet Cong forces, often ambushed from riverbanks, facing small arms, recoilless rifles, and rocket-propelled grenades. • Joint Operations with ARVN: The division frequently conducted joint patrols and assaults with South Vietnamese Army (ARVN) units, fostering interoperability and supporting local security efforts. • Decorations and Honors: Sailors and officers of RIVDIV-594 were awarded numerous commendations, including Bronze Stars and Navy Commendation Medals, for bravery and effectiveness in combat. • Innovative Tactics: The unit pioneered "stop and search" tactics, boarding suspicious sampans and junks to interdict enemy weapons and supplies, significantly disrupting Viet Cong logistics. • Casualties and Sacrifice: RIVDIV-594, like other riverine units, suffered casualties due to the hazardous nature of river patrols, including exposure to mines, ambushes, and booby traps. • Unconventional Challenges: Crews had to contend with environmental hazards such as leeches, snakes, and oppressive heat, as well as maintaining sensitive electronics in humid, muddy conditions. • Legacy: The unit’s experiences contributed to the development of modern riverine and littoral warfare doctrine, influencing the creation of the Navy’s current Riverine and Special Warfare units.
