Well, the only thing you forget is that they are not WW2 Germans, and thus the chances of Mars (or anyone else for that matter) making such items is fairly thin.
Yes, no one do a German naval combat unit (Marinedivison) or a air force ground unit (Luftwaffenfelddivison). But still miss boxes of Refugees, Norway, Bulgaria, Greek, Finish (and not the huge Strelets please) soldiers. And please not all in combat poses.
