The 2nd 90mm Antiaircraft Artillery Gun Battalion was a United States Marine Corps antiaircraft unit that was active during the 1940s & 1950s. Originally formed during World War II as the 9th Defense Battalion, the battalion took part in combat operations on Guadalcanal, Rendova, Munda Point, and Guam. Like most other Marine defense battalions, the unit was re-designated in September 1944, becoming the 9th Antiaircraft Artillery Battalion. Returning to the United States in 1946, the battalion was again re-designated, this time as the 1st Antiaircraft Artillery Battalion. The battalion received its final designation as the 2nd 90mm Antiaircraft Artillery Battalion on August 21, 1950. It was later decommissioned on September 15, 1956 at Marine Corps Base 29 Palms, California.[1]
