A group of students practice palm strikes during a self-defense class at the Transit Center at Manas, Kyrgyzstan, Dec. 3, 2011. The students learned basic blocking and striking techniques during the three-hour class. A second class, which takes place Dec. 10, is open only to females. This class will equip students with more advanced self-defense skills. (U.S. Air Force photo/Tech. Sgt. Tammie Moore)
