A U.S. Marine with Marine Rotational Force-Europe 18.1

A U.S. Marine with Marine Rotational Force-Europe 18.1 faces a final challenge during an Oleoresin Capsicum exposure course at Vaernes Garnison, Norway, July 13, 2018. The Marines spent three days in a classroom learning about OC and practicing riot control techniques before coming in contact with the substance. The course began with exposure to OC spray from an Mk4 container, followed by several riot control techniques including mechanical advantage control holds, baton drills, and spraying inert OC. Nonlethal weapons instructors then monitored the Marines for two hours to ensure they were decontaminating safely. (U.S. Marine Corps photo by Cpl. Gloria Lepko/Released)
