during a war between an alien race with a goal of taking all of earths water and during operation hammer head, a U.S battalion gets transported to equestria during urban fighting, in poor condition.
And somehow, some of the alien soldiers get transported to equestria as well. And this very well means that equestrian peace will come to a halt until its all over. (takes place after the final battle of Los Angeles)

Cancelled until further notice, ill see what i can do to keep this story alive.
