Joint force air component commander
Joint force air component commander (JFACC) is a United States Department of Defense doctrinal term.
It refers to a senior officer who is responsible for the air forces within a joint force; i.e., a military force composed of forces from two or more military departments. The term "air forces" encompasses aircraft from any service not already designated to specifically support ground forces (e.g., a marine air wing as part of a MAGTF or "organic" Army aviation assets).
