VMO-3, Camp Pendleton, Phu Bai,RVN.

Marine Observation Squadron 3 (VMO-3) was a United States Marine Corps observation and reconnaissance squadron formed during World War II and later reactivated at Camp Pendleton, California. During the Vietnam War, VMO-3 deployed to Phu Bai, Republic of Vietnam (RVN), in 1965, where it provided aerial reconnaissance, artillery spotting, and close air support missions using aircraft such as the OV-10 Bronco and UH-1E Huey. The squadron played a crucial role in supporting Marine ground operations in northern I Corps, including the defense of the DMZ and the Battle of Hue. VMO-3 remained active in Vietnam until 1969, after which it returned to the United States and was eventually decommissioned.
