Was once tasked to fly a group of "enemy" (our Sqn Rockapes) into Bruggen's TACEVAL by Puma. We used some obscure mission number callsign to contact ATC to check for circuit traffic, using the pretext that we were in transit and wanted to cross the MATZ panhandle, heading for the South. We then went "on route" and dropped down to operational height before coming in over the airfield perimeter at well below fifty feet. We flew straight to the Commcen, quickstopped over the middle of the flat roof, disgorging the Rocks. The two machine gun positions were well cammed, so much so that they couldn't lift the guns around to face inwards.
The Rocks took out both positions very quickly. A nice bonus for them was that some helpful person inside the Commcen opened the roof door to see what all the noise was about........ so the Rocks ran in and took out the whole lot.
We were supposed to then stop for a refuel but we decided to go to Laarbruch instead, the natives seemed a bit more friendly......
