Military aircraft are aircraft used by the military for a variety of purposes, such as combat, reconnaissance, transport, and training. The most common types of military aircraft are FIGHTERS, bombers, and FIGHTER-bombers. A FIGHTER is a type of aircraft designed primarily for air-to-air combat against other aircraft, while a BOMBER is an aircraft designed to attack ground or sea targets with bombs. FIGHTER-bombers are aircraft that combine the roles of both FIGHTERS and bombers.
