Okay, I'll never understand how they came up with this show, but if you can get past the Anime-ness, the attention to detail of the tanks, movement and historical references is amazing. My son turned my on to it and it's fun to watch with him. The idea is it's a girls school that teaches tank martial arts in competitions. It's flippin' weird. Their base is an aircraft carrier and they fight with a Pz IV, Stug III, 38(t), Lee and Chi-Ha (I think it is). It's so detailed that one girl is holding a copy of PIV Fibel and at the 'tank store' there are Tamiya models on the shelves.
Anyway, here's bit of intro that you guys should see, including a MAUS, Porsche Tiger:
