I guess that submachine guns, identified as "Bergman SMG", looks more like Suomi KP/-31. The flamethrower seems to be a Flammenwerfer 35 or Flammenwerfer 41 rathen than M1 as it has one large and one small balloon while M1 has two large and one small. Greg-Z (talk) 17:35, 4 April 2015 (EDT)
Note the german version does not have a back and front grip. Dudester32 (talk) 17:49, 4 April 2015 (EDT)
I'm fairly sure it's an M2, it's just the angle he's standing at that makes the second large tank look like it's not there in the top image; you can still see the side of the left tank below the middle one. In the one below you can see there's a full-size tank on the left, too. Evil Tim (talk) 18:15, 4 April 2015 (EDT)
