an Entity references as follows:
An aggressor squadron or adversary squadron (in the US Navy and USMC) is a squadron that is trained to act as an opposing force in military wargames. Aggressor squadrons use enemy tactics, techniques, and procedures to give a realistic simulation of air combat (as opposed to training against one's own forces). Since it is impractical to use actual enemy aircraft and equipment, surrogate aircraft are used to emulate potential adversaries.
