Tactical Air Control Party airmen hike at Wheeler Army Airfield's East Range to sharpen proficiencies necessary for upgrade training. When deployed, these young men who volunteered for the TACP career field are responsible for calling in close-air support and providing clearance for air assaults to ensure the right targets are reached. Stationed with Army combat units on the ground, they must be also prepared to administer first aid and survive in a hostile environment. (U.S. Air Force photo/Senior Airman Carolyn Viss)
