A portable control module autonomously positions a target deployed in a combat simulation course. The module chassis is bullet-resistant and angled to deflect errant shots, and encloses a control circuit having an adjustable target exposure delay, an adjustable target exposure duration, means for receiving a trigger signal representing movement of a human body, means for revealing the target when the exposure delay lapses after triggering, means for enabling, only when the target is revealed, hit detection means detecting a shot striking the target, and means for concealing the target responsive to earliest occurrence of the shot detection or lapse of the target exposure duration. The module may include means for relaying the trigger signal to other modules within a cooperative decentralized target control system. A method for the autonomous position control is also disclosed.
