OC! OC! OC! The MSG Students with Class 5-24 completed the OC spray portion of their training on Friday, marking their last major training event before graduation on September 27! The students undergo oleoresin capsicum spray training in order to understand the psychological and physiological effects the chemical agent has on a person. #marinesecurityguards #msgduty #msgschool #marines #training #ocspray #nonlethal #students
