MAG 12 was brought to the Philippines by the request of Admiral "Bull" Halsey when he said, I had had under my command in the South Pacific a Marine Air Group which had proved its versatility in everything from fighting to blasting enemy vessels.
Kinkaid's complaint of insufficient air cover prompted me to take a step which was more than a liberty; to a man of meaner spirit than MacArthur's it would have seemed an impertinence.
[3] Through the end of the Korean War, the group participated successfully in numerous operations and accumulated over 80,000 effective combat sorties against enemy troops, installations, vehicles and countless other vital targets.
In May 1965, MAG-12 deployed to Chu Lai, Vietnam, to support Marine infantry and other allied forces in their engagements against the Viet Cong and the North Vietnamese Army units.
From this base, MAG-12 has conducted numerous operations throughout the WESTPAC area and participated in hundreds of joint service training exercises, continually honing its combat skills.
