Sgt. Nestor Morales, a Chemical, Biological, Radiological, Nuclear (CBRN) specialist with the 149 CBRN Company, 49th Military Police Brigade, California Army National Guard, returns fire at opposing forces attacking his unit's tactical assembly area during a Combat Support Training Exercise (CSTX) at Fort Hunter Liggett, Calif., July 12, 2017. Nearly 5,400 service members from the U.S. Army Reserve, U.S. Army, Army National Guard, U.S. Navy, and Canadian Armed Forces are training at Fort Hunter Liggett as part of the 84th Training Command's CSTX 91-17-03; this is a unique training opportunity that allows U.S. Army Reserve units to train alongside their multi-component and joint partners as part of the America's Army Reserve evolution into the most lethal Federal Reserve force in the history of the nation.
