Girls und Panzer/Headscratchers

Why did the Selection University Team accept the match with Oarai in Der Film?

 * Someone needs to give the University Team in Der Film a good long What the Hell Hero Speech ... they're the heroes of their own story, but playing with the ridiculous set of advantages they do — thirty-to-eight odds and much more advanced equipment, in an annihilation battle — isn't remotely sporting behavior. Basically, they've agreed to be hit-women on behalf of a Obstructive Bureaucrat from MEXT. It seems none of them thought to complain, "Wait a minute! These odds make it look as if we can't win fair and square!" and refuse to go along with the official's scheme. So much for tankery making them better women.
 * The head of the team, Chiyo Shimada, is much like Shiho Nishizumi, a powerful matriarch of a major tankery style with a drive to win above all else. She is using this match as an opportunity to put one over Shiho -- she calls her daughter Alice (commander of the University team, and similar in many ways to Maho and Miho) ahead of the match and specifically instructs her to "destroy the name of the Nishizumi style".  The rest of the University team may be similar in character to Kuromorimine (prior to Oarai's victory), composed of enough students who believe in victory as the ultimate goal (as Erika Itsumi did -- Azumi, Mayumi, and Rumi behave this way) or who pretend to out of fear (as many other Kuromorimine commanders did) to keep the rest in line.  As for tankery making people better women (or not)...yeah, the more we see of the tankery world, the more it seems that girls turn out okay in spite of it.
