[BF-109 F4]

Thank you for all your helpful replies. That's what I love about this site, sometimes a discussion on one topic leads to answers for another.

Impressive pictures, Bf-109 F-4. I have to admit, as Dorkfish pointed out, I didn't look under "armor," only under "artillery." Is the Karl mortar under "armor" because it has tracks? Perhaps Oleg saw it as the Sturmtiger's big brother?

I don't understand why the Karl Gerat is only in the armor list. All other tanks are in the artillery except this beast. After all it should be considered more as artillery than armor. It's an artillery piece, not something that you would put in the middle of the battlefield.
