Richard Cheeks (left), heavy equipment operator, R4OG, 1st MLG, during IED awareness training aboard Camp Pendleton, Calif., March 10, 2014, in preparation for an upcoming deployment. While in Afghanistan, their mission is to identify what equipment they can use, bring it back, and reallocate it to save money and prepare for future operations.. As they accomplish this, the Marines will operate in an area known to have IEDs. IEDs can be made with everyday household items, making it a cheap and effective weapon for the insurgents to employ against U.S. troops.
