Mighty Ninety gets a little muddy
Maj. David Sorrels, 90th Communications Squadron commander, low crawls under a log through mud Aug. 29, 2015, during the second annual F.E. Warren Air Force Base, Wyo., mud run. The five-kilometer course was filled with various obstacles, with mud and water increasing the difficulty. (U.S. Air Force photo by Airman 1st Class Brandon Valle)
