In short, combat control officer on the ground commands his buddy aircraft, or pair to position them for an attack of the enemy from behind preferably undetected by the target. It is on different frequency than home ATC, and there may be different combat controllers during one sortie depending on early warning sites structure so a good point for simulated missions is establishing communications with different guys on the ground, maybe adding personality to each voice.
Basically, instructions for course and altitude before takeoff, then correcting messages which course and altitude to be on as "heading, altitude", and shorter commands like "left 10". Closer to target control officer says more precise commands like "turn right roll 30 to course 270" to specify the speed of needed corrections. In range of fighter's radar: callsign, enable emission. Pilot: target on radar/got visual. Controller: proceed to engage, egress right/left to course, altitude.
