Staff Sgt. Edward Garwick, 628th Civil Engineer Squadron explosive ordnance disposal technician, uses a knife to strip a wire used to detonate a simulated improvised explosive device during a routine training exercise Jan. 8, 2013, at Joint Base Charleston - Air Base, S.C. Command wire is a hair-thin, bare copper strand that only the sharpest eye can see. The training equips EOD members in how locate and pinpoint these command wires that may be attached to explosive devices in remote areas during deployments.
