The A.T.A.C. (Agile Tactical Air Component) is a flying assault vehicle used by the Helghast, capable of attacking vehicles or infantry. It is also a prototype fighter aircraft transported to Vekta for combat trials by the Elite Guard. Though originally built to offer room to a single pilot, later models were designed to be operated unmanned via remote control, due to a high number of crashes during live tests. The aircraft is a relatively small, fast, and extremely maneuverable attack vehicle that is armed with devastating array of firepower.
