| - Forward air control is the provision of guidance to Close Air Support (CAS) aircraft intended to ensure that their attack hits the intended target and does not injure friendly troops. This task is carried out by a forward air controller (FAC). The rugged jungle terrain of South East Asia readily hid enemy troop movements. U.S. fighter-bombers were so fast that pilots had great difficulty in distinguishing between enemy troops, friendly troops, and civilians. Forward air controllers directing air strikes thus became essential in usage of air power. Visual reconnaissance formed the core FAC mission during the Vietnam War, as the FAC flew light aircraft slowly over the rough terrain at low altitude to maintain constant aerial surveillance. By patrolling the same area constantly, the FACs grew very familiar with the terrain, and they learned to detect any changes that could indicate enemy forces hiding below. Tracks on the ground, misplaced vegetable patches, an absence of water buffalo, smoke from cooking fires in the jungle, too many farmers working the fields—all could indicate enemy troops in a vicinity. Flying low and slow over enemy forces was very dangerous; however the enemy usually held his fire to avoid discovery. Each of the O-1 FAC aircraft originally used carried three different radios for coordinating with everyone involved in an air strike: an FM radio for the ground forces, a UHF radio for the fighter aircraft, and a VHF radio for contact with the Air Force Tactical Air Control Party to coordinate approvals and requests for air support. The FAC radioed for strike aircraft after spotting the enemy. He marked the target with smoke grenades or white-phosphorus rockets to pinpoint targets. After directing the fighter-bombers' attacks, the FAC would fly low over the target to assess the damage.
