Holy smokes, that's awesome!
Someone beat me to the comment on the sign. Ah well.
First thing that jumped out at me (after I got over the awe of seeing this beautiful level of detail) was, looks like you've got two infantrymen and one tanker (or StuG'er) in there. The grunts are bundled up but the tanker isn't. Is he a little out of place without winter gear?
He does look cold, though, so maybe not.
