OICCRVN

The OICCRVN (Operational Intelligence Command Center, Republic of Vietnam Navy) was established in the late 1960s during the Vietnam War to coordinate naval intelligence and operational planning for the Republic of Vietnam Navy (RVNN). Its primary mission was to gather, analyze, and disseminate intelligence on enemy maritime movements, supporting riverine and coastal operations against North Vietnamese and Viet Cong forces. The OICCRVN worked closely with U.S. Navy advisors and participated in joint operations, such as Operation Market Time, to disrupt enemy supply lines along the coast and inland waterways. The unit played a crucial role in enhancing the effectiveness of RVNN operations until the fall of Saigon in 1975.
