USS BOXER, AT SEA (April 6, 2016) U.S. Marine Sgt.

USS BOXER, AT SEA (April 6, 2016) U.S. Marine Sgt. Steven Spangler, a ground sensor operator with the 13th Marine Expeditionary Unit, moves along a barrier as he clears a simulated room within a "tape house." A tape house is an adjustable training aid made with cloth, cord or other barriers representing walls in a building. The adjustable layout of a tape house allows Marines to learn different techniques and movement patterns for clearing rooms in an urban environment first hand. The Boxer Amphibious Ready Group /13th MEU is currently deployed to the 5th Fleet area of operations to support regional stability and security. (U.S. Marine Corps photo by Sgt.
