Historically, Combat Controllers are usually more involved with air traffic control than with targeting.

The Air Force has Forward Air Controllers (historically both on the ground and in the air) who actually direct airstrikes. When they do their job well, friendly fire incidents are greatly reduced and bombing effectiveness enhances. But when they make a mistake, it isn't pretty.

From Chapter 4 of the Army FM 1-111

(2) Naval gunfire and close air support. Naval gunfire and CAS can provide the same fire support as FA. When naval support is available, the FSE of the aviation headquarters is provided a naval gunfire liaison team to control the support. An Air/Naval gunfire liaison officer or team may not be available. If so, the fire support officer (FSO), fire support team, scouts, or aerial fire support observer (AFSO) must control the naval gunfire. A forward air controller (FAC) or tactical air control party (TACP) from the the Air Force or Marine TACP normally would provide terminal control of CAS.
