I have recently been reading the book Tank Men by Robert Kershaw. Among other things, it says that Monty said the Sherman with its 75mm gun was "all we require". I find that extraordinary as by 1943, the newer German Panzers with their 88mm gun were vastly better. I know that some Sherman Fireflys were produced with the 17 pounder gun but nowhere near enough. Given the US manufacturing capabilities, I dont understand why Monty took the view he did. Surely he could ( and should) have said we need all Firefly versions - or is that a symplistic view. Can any one explain why the Sherman with its 75mm gun was decided as being acceptable - after all, Monty wasn't a Tanker!
