AL ASAD AIR BASE, Iraq -- Tech. Sgt. Antonio Queen, 438th Air Expeditionary Group crew chief, inspects fasteners on the leading edges of an A-10C Thunderbolt II wing here. According to Sergeant Queen, the fast pace combat environment here makes it critical that aircraft are turned around quickly. The upgraded A-10C Thunderbolt IIs he maintains are the first to fly in combat. Sergeant Queen is deployed from the 175th Wing, Maryland Air National Guard, Baltimore. (U.S. Air Force photo/Tech.
