That simply doesn't sound credible on face value. Sorry.
100% exactly what happened.
a squaddie called HTC (had similar incident) and per them, if the abuse is not on 200 or country channel I.E. something the public can see, and the profanity is not spelled correctly.. there is no corrective action that can be taken, just squelch them.
and if you DO use the report function on them for doing as said above, you are in the wrong, not them.
