This replica of Star Wars’ "R2-D2" astromech droid brought a smile to the faces of many as it cruised through the main corridor of the McDonald Army Health Center at Fort Eustis, Va., Aug. 23, 2013. Matt Hammer, an emergency medical technician at the health center, built the replica by hand, and frequently showcases it in the community. (U.S. Army photo by Marlon Martin/Released)
