The307th Operations Group is an Air Reserve Component of theUnited States Air Force. It is assigned to the307th Bomb Wing,Air Force Reserve Command, stationed atBarksdale Air Force Base, Louisiana.

In the postwar era, the 307th Bombardment Group was one of the USAAF bombardment groups assigned toStrategic Air Command on 4 August 1946, the group being activated as a redesignation of the498th Bombardment Group due to the Air Force's policy of retaining only low-numbered groups on active duty after the war. The group deployed toOkinawa during theKorean 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.

The 307th Operations Group was activated on 8 January 2011. Its mission is strategic nuclear deterrence and global strike.

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. During withdrawal. gunners of the Group destroyed 31 of the 75 attacking aircraft, probably destroyed 12 more and damaged 10 in an air battle that lasted 43 minutes. This daring raid, made on 29 March 1944, neutralized the Japanese airfields, making possible long range flights without fighter protection, The other Presidential Unit Citation was awarded for the successful strike at the Baltkapapan Oil Refineries inBorneo on 30 September 1944.
