Kinda surprised Revell Germany has not banged out one. Lots of variants to choose from too.
Well basically there are only three
German/Sanka (Transporting wounded)
Most differences are internal and often "not visible on the typical Revell detail level" (Don't get me wrong, I like many of their kits). Or they are in the "Rüstsatz" (Equipment package) that is fitted to the rail system in the back and/or the roll bar.
Still, a solid "basic vehicle" would be VERY useful (as would be a Munga) and if priced like their "Wolf" I'd order at least three and a roof section...
