GRISSOM AIR RESERVE BASE, Ind. -- The blast doors and wires of an electronic control device can be seen as Staff Sgt. Justin Coe fires the ECD at an exercise dummy. Coe, a 434th Security Forces Squadron security response team member, and other Grissom security personnel received training on such devices that they will begin carrying on-duty.
