Master Sgt. Steven Hawkins, 11th Security Forces Group NCO in charge of training, shows Airman how to rinse Oleoresin Capsicum spray from their eyes June 14, 2012 during a training session at Joint Base Andrews, Md. Security forces Airman are exposed to OC spray prior to being certified to carry it so they are aware of its affects on whomever they spray, as well as themselves. OC spray is an extremely effective less-than-lethal tool that can be utilized to quell a situation without having to otherwise resort to lethal force.
