Sherman Firefly was probably the best British tank of that war, with respect to the Comet. The fitting of the 17 pounder gun made it capable of dealing death at a distance to any German tank. Whilst retaining the high profile, weak armour and petrol engine that gave the Sherman the lovely nickname " The Tommy Cooker", or "The Ronson"
It was a Firefly that ended the life of fanatical Nazi tank ace SS Oberscharfuhrer Michael Wittman, thanks to Captain Tom Boardman of the Northants Yeomanry who ambushed him in August 1944. The Firefly he had with him brewed 3 Tigers with 4 shots.
Generally each troop of British Shermans would have one Firefly attached, known as the 'Charlie' due to it's callsign.

By all accounts the Centurion provided excellent service in both Korea and Israeli - Arab conflicts.
