An Afghan Air Force tactical air controller scouts notional targets for MD-530 helicopters during a training exercise at Camp Shorabak, Afghanistan, Dec. 18, 2017. Several ATACs enhanced their aircraft-directing skills during the exercise with assistance from coalition advisors in preparation for future operations in Helmand province. Tactical air controllers often travel with ground force elements on the battlefield to direct airstrikes onto targets, allowing for better maneuver and safety of ground forces.
