Lance Cpl. Mark W. Briggs, left, Lance Cpl. Tyson G. Bainum and Lance Cpl. Tyler Steffins with E Company, 2nd Battalion, 7th Marine Regiment, halt behind a wall moments before rushing to a landing site where they will be extracted in UH-1 helicopters from an urban training range at the U.S. Army Yuma Proving Ground in Arizona during a helicopter raid exercise Oct. 12, 2009. Sixteen Marines landed on the outskirts of the range in four UH-1 helicopters and stormed the buildings from all sides searching for two insurgent leaders, simulating a mission they could be called to perform during their next deployment. The battalion, based in Twentynine Palms, Calif., is scheduled to deploy with the 31st Marine Expeditionary Unit in early 2010, with E Company assigned to specialize in helicopter insertions and raids. Briggs, 25, is Salt Lake City-native, Bainum, 20, is a native of Canyon, Texas, and Steffins, 21, is from Marysville, Wash.
