Utilitiesman 3rd Class Daveeth Macias from Naval Mobile Construction Battalion (NMCB) 3 takes direction from his team leader during a middle-of-the-night intruder on camp drill designed to test the battalion's ability to track and apprehend enemy invaders. NMCB 3 is conducting their final graded field training exercise (FTX), testing the battalion's command and control functions through a variety of realistic scenarios encountered during Seabee deployments. The Seabee battalion provides commanders and Navy component commanders with combat ready warfighters capable of general engineering, construction and limited combat engineering across the full range of military operations. Fort Hunter Liggett is the largest installation in the Army Reserve, with more than 160,000 acres of mountains, valleys, rivers, plains and forests. It provides maneuver areas and state of the art training facilities for active and reserve Army units, and for all components of the Department Defense and several allied nations (U.S. Navy photo by Mass Communication Specialist 1st Class/RELEASED).
