Lance Cpl. Armando Moreno, a chemical, biological, radiological and nuclear specialist with Headquarters and Service Company, 4th Light Armored Reconnaissance Battalion, walks toward a simulated weapons cache that includes sarin gas at the Army National Training Center Fort Irwin, California, July 12, 2014. The CBRN Marines used their equipment to test the area for contaminants in the air and ensure the simulated gas was contained. This was part of 4th LAR’s annual training, which was the first time since the battalion’s deployment to Afghanistan in 2009 – 2010 that the companies within the battalion worked together.
