Superb story, as they say, you couldn't make it up!
Glad you're okay though FBOAB, or at least physically okay.
Only one that I can think of that is vaguely familiar is an old friend of mine rotating a tank gun in an enclosed space and smacking the barrel off something, the something was more solid than the gun barrel and this resulted in a slight but expensive bend. Ideal for firing shells round corners but apparently there ain't much call for that in the war zone!
