Which brevity word is used to positively denote known enemy aircraft?

The term "Bandit" is used as a brevity word in military communications specifically to positively identify known enemy aircraft. This designation is critical in combat and air operations to ensure clarity among pilots and ground control regarding the status of aerial threats.

Using "Bandit" conveys that the aircraft in question is confirmed as an enemy, allowing for appropriate tactical responses. In contrast, other terms like "Target" or "Contact" may lack this definitive identification of hostility, as they can be used in broader contexts that do not specify whether an aircraft is an enemy or friendly. "Hostile" is also a term that indicates an adversarial relationship but is not as commonly used in the same explicit sense as "Bandit." Hence, choosing "Bandit" accurately captures the intended meaning of identifying a known enemy aircraft.
