The 1st Provisional Antiaircraft Artillery Group was a provisional unit that served as the headquarters for all United States Marine Corps antiaircraft battalions that participated in the Battle of Okinawa. The group was formed on Kauai, Territory of Hawaii in November 1944 under the command of the III Marine Amphibious Corps. For the Battle of Okinawa, the group was under the command of the 53d Antiaircraft Artillery Brigade of the Tenth United States Army and was responsible for air defense of the area surrounding Yontan & Kadena Airfields. Following the end of the war, the group returned to the United States and was decommissioned on December 5, 1945.[2] To date, no other Marine Corps unit has carried the group's lineage and honors
