 I'm FC 3 Wellamon, the USS Cole, and I'm about to get pepper spray. O-C-O-C-O-C! Sailors on board the USS Cole during the Naval Security Force Sentry, or NSFS, feel the effect of O-C spray to learn what it is like for an assailant that has been sprayed. Petty Officer Datka tells us more in the course. O-C is pepper spray, as everybody else knows it. It's been used since the time of the Chinese back in 2000 B.C., when they'd crush up peppers and throw them in their enemy's face. Participants navigate the course through mock takedowns, battle strikes and blocks, and what is known simply as the Red Man. Having a time where we have to go through a painful situation like this helps you bond together as a team in a way that I don't think you can simulate with any other situation. On board the USS Cole, Petty Officer Christopher Krukey, Suda Bay, Crete.
