The 391st Fighter Squadron is part of the 366th Fighter Wing at Mountain Home Air Force Base, Idaho. The squadron participated in combat missions in World War II and the Vietnam War, provided air defense in Korea and Japan from 1968 to 1971, and continues to provide tactical air command for the United States Air Force.

## History
### World War II

The 391st flew combat missions in the European Theater of Operations from 14 March 1944 to 3 May 1945.

### Vietnam War

The squadron flew in combat in Southeast Asia from 2 February 1966 to 21 July 1968.

### Pacific air defense

It provided air defense in Korea and Japan from 22 July 1968 to 14 February 1971.

### 2013 sequestration

Air Combat Command officials announced a stand down and reallocation of flying hours for the rest of the fiscal year 2013 due to mandatory budget cuts. The across-the-board spending cuts, called sequestration, took effect 1 March when Congress failed to agree on a deficit-reduction plan.
Squadrons either stood down on a rotating basis or kept combat ready or at a reduced readiness level called "basic mission capable" for part or all of the remaining months in fiscal 2013. This affected the 391st Fighter Squadron with a stand-down grounding from 9 April-30 September 2013.
