I have an idea. Whats about 2 MGs for the ostheer?
the "normal" MG42 and a MG 34 who can disguise like the PAK38 from the wehrmacht.

And i think the tiger is a must have for the ostheer and so it should be that the ostheer tiger is not so strong like the tiger of the wehrmacht but dont get a limit ( the IS2 have no limit too)

At the end I found a nice link about vehicles in the ww2
