Ouch, the 3DCG for both the tanks and the terrain is jarring...
So, in this future/alternate world, commanding a tank is a sign of being a Japanese lady :D And there will be a World Cup competition soon...
The plot is totally non-sensical but Fumikane being involved makes it at least a "try a bit longer". I've got a feeling this will be like Upotte! where it's actually a watchable show once you get past the logic of the show.
And the ending scene with the aircraft carrier was a total WTH!?
