Done 10yrs on that gun, Never heard it called that! I called it many a thing over the years but I loved it. It was like a freezer in the winter until I managed to get a small heater for it. I also had double BV'S and a tv whilst dry trg.
Not generally, unlike the narrator of that cringe-making video.
At various times individual vehicles guns may have attracted a full string of expletives, such as the detachment of the gun which threw both tracks in a night move across Hohne ranges in the pouring rain.
At one point a rather erudite FOO tried to name the FV432 OP vehicles after ancient warriors, to compete with the fancy names of the Hussar and Lancers tanks but "Tiglath-Pileser III" and "Ashubanipal" seemed a little overblown for a mess tin on tracks. Florence, Dougall and Mr Rusty seemed more appropriate.
