Bradley Ralston, a counter radio-controlled electronic warfare (CREW) field service representative with Tobyhanna, assembles a CREW system antenna at Bagram Air Field, Afghanistan on March 30, 2014. CREW systems function essentially as a cell phone tower; only in reverse. Instead of projecting a signal to receive, they ‘jam’ or disrupt all incoming radio frequencies within a designated spectrum.
