Future Armour

[McG]

Europe seems to be favouring 40 mm for its future mid caliber cannon. The US Army seems more interested in 50 mm to 75 mm which is getting outside the autocannon sizes.

75mm is a Sherman with an autoloader.

I think the 6 pdr Troop is exactly the right place for a 105/120 gun. Not so much for knocking out tanks, as you saw autocannons, ATGMs and LAM/OWUASs have probably got that covered. But a few larger guns for demolishing obstacles from a distance might come in handy. No?

Or maybe put a demolition gun on an engineer vehicle, like the L9 on the Churchill and Centurion AVRE.
