the fact that the German tanks were far superior than anything the allies had
Sherman were under armoured/gunned compared to the germans (& russians, but luckily were weren’t fighting them) but they didn’t break down. Also the majority of the early panzer weren’t that great, and IIRC more Sturmgeschütz (non-turreted version) were produced and used than tanks, cause they were cheaper
So yes and no, considering there were tank battles that the germans destroyed more of their own extremely capable but bloody unreliable tanks than the enemy, (so they weren’t captured by said enemy)..
Hitler was a ‘big is good’ nut… I’d always wondered by the allies didn’t just take a captured 88 and develop their own version/copy.. the tiger was ‘so big’ as it was designed around the turret that could house the 88.
