RILEY XANTEN II

Marines from Marine Forces Reserve help each other to quickly put on their Mission Oriented Protective Posture gear during a chemical, biological, radiological and nuclear defense training simulation aboard Naval Air Station Joint Reserve Base New Orleans, Feb. 5, 2015. Once a chemical agent is detected, Marines must urgently equip and secure their protective gear to prevent or minimize the possibility of contamination. The CBRN defense training equips Marines from diverse units, with the proper knowledge and readiness needed to handle a real combat zone situation. (U.S. Marine Corps photo by Lance Cpl. Ian Ferro)
