Rigga you said "Remember that we once heavily practiced "Battle Damage Repair" techniques - but we never dared to use them!"
Slight thread drift (for which I apologise) but I had a mate who was tasked to do just that. It was a long held belief that a hole in a Radar aerial could be "patched" with little or no loss of signal strength. To prove or disprove this a spare Watchman (IIRC) aerial was signed out then shot at (no loss of signal), holed with a small amount of PE (again no loss) then attacked with a larger amount of PE. The Michael Caine line can be inserted here. Once they had swept it all together it only remained to nominate someone to return it to stores with an appropriate F731.
