Camp Joseph T. Robinson. Wearing components of the multiple integrated laser engagement system (MILES), Sergeant (SGT) Mark Peterson, from the 314th Security Police Squadron participates in Exercise SAFE DEFENDER ONE as a member of the aggressor force. He is armed with an M16A1 rifle equipped with MILES. 29/06/1984.

Edit: Keen eyed viewers may notice the rifle lacks a forward assist, despite being labeled in all places in the original photo description as an M16A1. I suspect the rifle uses a Colt 603 (M16A1) lower given that it is fully fenced, and a USAF M16 Colt 604 upper. The military would consider this an M16A1 despite the sort of in-between configuration.
