Soldiers from the 3rd Infantry Division recently enhanced their capabilities to combat threats from radio-controlled explosive devices, which are used to harm service members.Ten soldiers completed the division’s Counter-Radio Controlled Improvised Explosive Device Electronic Warfare Specialist Certification, or CREW course, on July 11 on Fort Stewart. The newly certified soldiers work at the company and platoon levels, where there is no electronic-warfare specialist assigned.Four electronic warfare noncommissioned officers from the 4th Infantry Brigade Combat Team led the 40-hour course, which included training on the Thor III, Duke V3 and the Baldr, CREW systems currently used in Afghanistan to help keep service members safe during convoys and security patrols.“The instructors have been awesome,” said Sgt. Justin McEwen, a cavalry scout with Troop B, 6th Squadron, 8th Cavalry Regiment, 4th IBCT. “Any questions, they’ve been able to answer right on the spot, and if they didn’t know the answer … they had the material here (available).”The course covered how to operate, troubleshoot and maintain the three systems.“They are the main systems that we use when we touch down in theater,” said Staff Sgt. Michael Fernandez, one of the instructors and the electronic warfare specialist for 3rd Battalion, 7th Infantry Regiment, 4th IBCT. “We always have to have these systems in play when we are outside the wire.”“Electronic warfare is so demanding, and it changes every day,” said Sgt. 1st Class Robert Bennett, an electronic warfare noncommissioned officer for the 4th IBCT.Bennett, a native of Rome, Georgia, emphasized the importance of the training and the electronic-warfare mission. “We need the battalion electronic warfare NCOs to push harder to their commanders the need for these CREW specialists,” he said.
