A couple of things..
The infantry gun isn't a 15 cm sIG 33,a it's a 75mm leIG 18 
The flamethrower can't be a Flammenwerfer 35 because of the arrangement of the tanks, it looks more like a Flammenwerfer 41. It actually looks like the flamethrower was built for the movie because if you examine it closely it only has a passing resemblance to real German models. Go to the bottom of this page  to see pics of German flamethrowers.--Phillb36 03:46, 14 May 2009 (UTC)
