Ex-Army Ranger Adal Lupe has known nothing but war for the past two years of his life. Said life has been a day to day struggle, with no guarantee that he'll live to see the next sunrise. In fact, by all rights, he just saw his last.
So when he wakes up in Equestria, he'll soon find that there are some challenges far greater than surviving in a time of war.
Note: Did some editing on the first chapter, hopefully for the better.
