307th Operations Group

The 307th Operations Group is an Air Reserve Component of the United States Air Force. It is assigned to the 307th Bomb Wing, Air Force Reserve Command, stationed at Barksdale Air Force Base, Louisiana.

In the postwar era, the 307th Bombardment Group was one of the USAAF bombardment groups assigned to Strategic Air Command on 4 August 1946, the group being activated as a redesignation of the 498th Bombardment Group due to the Air Force's policy of retaining only low-numbered groups on active duty after the war. The group deployed to Okinawa during the Korean War and was awarded the Republic of Korea Presidential Unit Citation for its air strikes against enemy forces in Korea. It was also awarded the Distinguished Unit Citation and several campaign streamers.

Two Presidential Unit Citations were awarded to the Group during World War II, one for action in the bombing of the Island of Truk, the most heavily defended and strongly fortified Japanese base in the Pacific.
