A Japan Ground Self-Defense Force member visiting the annual Training Expo at Camp Hansen, Okinawa, Japan tests out the Instrumental Tactical Evaluation Simulated System on Friday, April 29, 2016. This recently updated system works almost like the popular game, "laser tag," where a laptop traces the marksmanship of the shooter. This training can be recorded and handed back to the unit on a CD to evaluate performance. - A Japan Ground Self-Defense Force member visiting the annual Training Expo at Camp Hansen, Okinawa, Japan tests out the Instrumental Tactical Evaluation Simulated System on Friday, April 29, 2016.
