ESS course enhances defender capabilities
Airmen 1st Class Cameron Welsh and Jason Caywood, both 4th Security Forces Squadron patrolmen, set-up a wide area surveillance monitor during an electronic security system exercise on Seymour Johnson Air Force Base, N.C., Jan. 22, 2010. When used to maintain a secure perimeter, the monitor captures thermal imaging if there is an intruder within the area being monitored. Welsh is from Galion, Ohio, and Caywood is from Woodward, Okla.
