The mission of military jets is to provide air support for ground forces. This includes providing reconnaissance, surveillance, and close air support for troops on the ground. Military jets are also used for offensive operations such as air-to-air combat and air-to-ground strikes. They are also used for defensive operations such as air defense and air superiority. The term AIRS is an acronym for Air Interdiction, Reconnaissance, and Surveillance, which are all activities that military jets are used for.
