Hello malecontrol,
I appreciate your political problems, but let me put it this way.
Years ago, when at a mjor airport in the North of England, we had an ACR6 radar in the tower. At night aerodrome and appproach/approach radar was performed by one man in the tower. To do this the controller had to have aerodrome, approach and approach radar ratings and validations. He could then use, as you put it, radar phraseology.
