Sgt. Dustin N. Heath, assigned to the 155th Infantry Regiment of the Mississippi National Guard, wears MILES gear as he pulls security during a multi-echelon integrated brigade training exercise in June at Fort Hood, Texas. MILES is a training system that provides a realistic battlefield environment and tactical engagement simulation for direct-fire, force-on- force training. The MILES Laser Tag Utility app enables Soldiers training with the system to test, configure and troubleshoot their equipment. (Mississippi National Guard photo by Sgt.
