Just a guess, but probably a prior-mil slip of the tongue, during the heat of the battle. Very few places (other than Navy) still have PAR radars. He may have meant ASR or simply "I can't see the airport, line me up."

PARs can be done with and without heading reference. It assumes you have at least a standby ADI.

No-Gyro approaches are initiated by the pilot. "I need no-gyro vectors for an (ASR/PAR)." For no-gyro, the controller would say "All turns on final are half-standard rate." (15 degrees of bank in my airplane). Once lined-up on final, the controller would say "Turn left," then would say "Stop turn." Works pretty well with a trained pilot.

Can also be done for ASRs.
