I have heard that as well but that is all.Another story with tanks, how true, I cannot say, A squadron of tanks parks up a few hundred yard from a forest pub, The lads walk in, and are immediately told to fcukensee off by the boxhead gaffer, who has a reputation of hating the British military. The Sqn commander tries to be nice, and promises that his lads will behave like gentleman (?) no noise, no fuss, the gaffer says nein, big time, he will not have filthy Britishers in his pub.
A low rumble is heard, and a then voice, advising all to evacuate immediately, the sharp end of the main armament comes crashing through the pubs window, followed by a blank round, which blasts out all the windows, doors, and totally wrecks the bar, and does extensive damage to the medieval beer hall. True? who knows,... again I heard this story about 40 years ago.
