US Air Force SENIOR AIRMAN (SRA) Kyle Duncan, an M60 gunner assigned to the 137th Security Forces Squadron, Air Force Reserves, Oklahoma City, Oklahoma, blends in with his surroundings. He is camouflaged with his M60 mounted on a High-Mobility Multipurpose Wheeled Vehicle (HMMWV). This effective technique can surprise aggressors that might attack near his position during Contingency Support Operations Course (CSOC) 97-8. The Contingency Support Operations Course gives many airmen their first taste of how contingencies work, what is expected of them, and how to survive and operate under these conditions
