The Bagram Batman cheers on runners as they pass the half-way mark during a 5K road race commemorating the 105th Birthday celebration of the U.S. Army Reserve at Bagram Air Field, Afghanistan, on April 25, 2013. The Army Reserve, founded in 1908 as a reserve corps of medical personnel, includes 148 different military occupation specialties and accounts for almost 20 percent of the Army’s total force. There are currently more than 6,000 Army Reserve citizen-soldiers deployed abroad.
