Julian Torres, MWSS-371 supply chief, drill a pad onto a newly formed expeditionary airfield at Laguna Army Air Field in Arizona, during a predeployment training exercise, March 24, 2011. Fourteen MWSS-371 Marines practiced setting pads down while wearing full mission oriented protective posture gear to simulate a deployment scenario. The pads allow aircraft to land with minimal foreign object debris, making it easier to land and refuel. The Sandsharks' predeployment training also overlapped with exercise Crown Joule 3, a Marine Aircraft Group 13 training cycle that helps pilots gain experience for the squadron's deployment to Afghanistan in fall. - Sgt.

A memorial tribute that shows 35 explosive ordnance disposal Marines who have died supporting operations in Iraq and Afghanistan and on duty, stands at the Combined Explosive Ordnance Disposal Unit building at the Marine Corps Air Station in Yuma, Ariz., March 1, 2011. "Every EOD tech on this wall we know, either personally or we've worked with them," said Chief Warrant Officer 2 Simon Wade, unit officer in charge. "There's a story behind every one of these guys." When the wall was first dedicated, it was a simple one-faced structure that only had 19 faces on it, and wood cutouts of Iraq and Afghanistan. The wall has since expanded in commemorating the deceased, the country models far more detailed with the locations of major cities and rivers etched into them, courtesy of Marine Wing Support Squadron 371 combat engineers. - A memorial tribute that shows 35 explosive ordnance disposal Marines who have died supporting operations in Iraq and Afghanistan and on duty, stands at the Combined Explosive Ordnance Disposal Unit building at the Marine Corps Air Station in Yuma, Ariz., March 1, 2011.
