"The story takes place in a universe where girls participate in Sensha-dō (戦車道?, lit. "Way of the Tank"), the art of operating tanks, as a traditional martial art."
Well that's a shitty explanation. Traditional martial arts don't include a danger of killing everyone when a shell hits the ammunition compartment! But I suppose I'm asking too much if I expect a show about schoolgirls driving tanks to make any sense at all in the first place...
