The Tactician's Drone also known as Sentry Drone is a flying drone similar to an ATAC and is the Tactician's secondary badge. You can throw a beacon that emits a green flashing light, and a friendly drone will come in. It fires bullets at enemies with surprising accuracy and power, capable of scoring head shots (which nearly always result in a one-hit kill), even on moving or far away targets. They seem to be as powerful (but much more accurate) than the Sentry bots, and like them can spot and kill disguised saboteurs and cloaked scouts.
