Airman 1st Class Nicholas Groomes-Warren, 8th Security Forces Squadron response force leader, begins to strike an "adversary" to control the situation during the expandable baton training class at Kunsan Air Base, Republic of Korea, Sept. 26. Expandable batons are specifically used to deescalate a situation with the least amount of force necessary. The expandable batons are one of the tools used by Airmen as a non-lethal means to defend themselves. (U.S. Air Force photo/Staff Sgt. Rasheen Douglas/Released)
