Well that isn't actually true - not that raw calibre means anything when it comes to actual armour piercing capability until the advent of HEAT and HESH. In 1939, the average tank gun was in the 20-47mm range with 37mm being probably most common. The british went a bit higher with the 40mm 2pdr (which could handle any tank likely to be met until late '41). Average armour thickness would have ben about 25mm with the Matilda at the extreme end at 78mm and the various light tanks (PzKpfv 1's, various Vickers and so on) being in the 8 to 15mm sort of range. To give you some idea of just how deadly a 2pdr was to most german tanks, it's penetration at 1000m was 40mm - enough to penetrate the frontal armour of any Panzer III or IV built before the middle of 1941. It's replacement, the 6pdr (57mm) was a better penetrator of armour than the US 75mm gun but far less useful for anything other than killing tanks. -- You are currently subscribed to the "R/C Tank Combat" group.
