If you can’t find the video you want on YouTube, look elsewhere. (This is the complete recording of the song, not just the excerpt included in the eighth episode of Girls und Panzer (and censored on Crunchyroll). The missing section of the anime begins around 1:50.) ((Though the censored section is back on Youtube for now.))
So we’ve had girls with guns, girls as guns (or is that guns as girls?), girls with mecha, girls as combat aircraft, and now with girls with tanks. ((It’s actually not that new. See Those Who Hunt Elves — on second thought, don’t. It’s lousy; not even Kotono Mitsuishi could redeem it.)) It’s probably all just pandering to otaku, but perhaps there is something more sinister going on. If anime reflects reality, Japanese young men generally are either hapless dweebs or sparkly bishies and crossdressers. If you want to form an army, they’d be useless. You’d be better off drafting young women, who in Japan have talent for using the tools of war, and often magic, too. Girls und Panzer may be just the latest in a series of entertainments designed to accustom the Japanese to the idea of women as warriors.
At least one Chinese writer sees “evil intent militarism” in Girls und Panzer, though it’s difficult to follow the argument as interpreted by Giggle Translate. ((Giggle Translate insisted that the original language of the linked page was Irish.))
Mave-chan had combat aircraft as girls.
Ground Defense Force Mao-chan had elementary school girls with a tank, a jet, and a submarine. To battle cute aliens, send cute defenders, complete with Magical Girl henshin. Perfectly logical.
