Fred Keith Mahaffey was a United States Army four-star general who served as Commander in Chief, United States Readiness Command (USCINCRED) from 1985 to 1986 before dying of cancer.

In 1961 the United States Strike Command (STRICOM) was established at MacDill Air Force Base as a unified combatant command capable of responding to global crises. The name of the command was originally derived from the acronym for Swift Tactical Reaction In Every Known Environment (STRIKE). It integrated the CONUS-based forces of the Army's Continental Army Command and the Air Force's Composite Air Strike Force (CASF) and Tactical Air Command.
