A modern soldier(s) in a fantasy world.

I think a great story would be if a modern or futuristic soldier and their unit were teleported to a fantasy world. If you wanted it to be a fanfiction you could have them be teleported onto the hogwarts land or something with a tank or some sort of military vehicle, and have them combat magic with modern technology. I don't know, just a interesting thought. If you wanted to make it futuristic, you could have them have technology from a world war that ends the world, or after a apocalypse. You can make it whatever you want, but it's just an idea at the end of the day.
