U.S. Army Reserve Pfc. Darlin Valdez, a combat engineer with the 365th Engineer Battalion HHC?, provides care to a mannequin during a multi-echelon medical training exercise at Fort Indiantown Gap, Pennsylvania, June 24, 2023. The exercise consisted of three iterations where the opposing force ambushed a mounted patrol and the notional casualties were treated and transported to the battalion aid station for further care. The training provided an opportunity for Soldiers throughout the battalion to work together and test their skills in a realistic training scenario. (U.S. Army photo by Sgt. 1st Class Sarah Zaler)
