Girls & Panzer Movie

both have an all girl cast and are both about saving their school from shutting down. 

If you need more high-octane military action with cute fuwa girls, then this is definitely one of the best choices in my opinion. Do note that the GuP film is a sequel to the actual anime so, watch the actual anime first. In Girls und Panzer, it's tank on tank action (drifting woop). In Haifuri (might as well be known as "Girls und Kriegsschiffe"), it's ship on ship action (bigger guns, bigger boom).  

Cute girls doing cute battle things - and winning through some untraditional, amusing tactics 

If you want an anime about fighting with machinese that's both hype but also doesn't shy away from coming up with ridiculous ideas pushing the rule of cool to the limits, then you might enjoy these anime.
