U.S. Air Force Staff Sgt. Felicity Walker, 18th Security Forces Squadron trainer, test sprays the OC spray for demonstration during Taser and oleoresin capsicum (OC) spray training July 20, 2017, at Kadena Air Base, Japan. The OC spray is similar to pepper spray, and induces a burning sensation to the affected region of the body. (U.S. Air Force photo/ Airman 1st Class Greg Erwin)
