Infantry Boys meet the Tankery Girls

This is a story that I had in my mind for a good minute and decided, what the hell, I might as well write it out. Quick summary is that in America, high schools take part in the also using WW2 equipment, but are more of a boots on the ground sort of approach, and when they both come together, you get closer to what a real battle looked like. OC/Harem, let me know who should be in.
