Oh dear, sorry. 'Twas me wot said 'Rocks' and 'Pongoes'. Should have known better.
But my original objection was that the Beeb (oops, sorry BBC) was saying the Army (with a capital A) was doing it. That says to me, a unit of the Army, not the Air Force or the Navy. Had they put 'army' (sometimes shorthand for 'military'), that would have been more acceptable. But when I investigated, it was confirmed that it was the RAF Regiment, aka (fondly) Rockapes or just Rocks. Perhaps it was the RAF Force Protection Centre, although I haven't yet been able to establish that. But it is the RAF Regiment that is tasked with protecting airfields. So the excellent Rocks should surely get the credit on this occasion.
As for Pongoes - well, that is a slightly more insulting term. But still fond!
