River Squadron Five

• Vietnam War Origins: River Squadron Five (RIVRON 5) traces its origins to the Mobile Riverine Force (MRF) concept developed by the US Navy and Army in the Vietnam War, designed to conduct "brown water" operations in the Mekong Delta’s complex riverine environment. • Brown Water Navy: RIVRON 5 was part of the so-called "Brown Water Navy," operating in shallow, muddy inland waterways where traditional blue-water ships could not go, using specialized patrol boats and monitors. • Patrol Boat River (PBR) Operations: The squadron was equipped with PBRs, fast, heavily armed boats that patrolled rivers, interdicted Viet Cong supply lines, and provided fire support for ground troops. • Joint Operations with Army Units: River Squadron Five worked closely with US Army infantry in the 9th Infantry Division, deploying together as part of joint Army-Navy mobile riverine task forces. • Reactivation for Modern Missions: RIVRON 5 was reactivated in the early 2000s to support riverine operations in Iraq, reflecting the persistent need for riverine capabilities in modern conflicts. • Al-Anbar Operations: During Operation Iraqi Freedom, RIVRON 5 conducted security operations on the Euphrates River in Al-Anbar Province, disrupting insurgent supply lines and supporting Marine ground forces. • Combat Action Ribbon: Sailors of RIVRON 5 earned the Combat Action Ribbon for their direct engagement with enemy forces in Iraq, marking the return of “brown water” combat for the US Navy after a long hiatus. • Innovative Training: The squadron developed specialized training in riverine tactics, including navigation, ambush response, and coordination with helicopters, to adapt to the unique challenges of inland waterway combat. • International Partnerships: River Squadron Five participated in joint training and operations with allied and partner nations, sharing expertise in riverine warfare and strengthening coalition capabilities. • Legacy and Honors: RIVRON 5’s legacy is honored by veterans and recognized in naval history as a symbol of adaptability and innovation in naval warfare, from the Mekong Delta to the rivers of Iraq.
