This story takes place in 2027.
In 2025 world war III broke out between the United States and The Korean Republic with all their allies (they fought without the nuclear weapons). USA President has the order to send new soldiers to save the island which is in the Atlantic Ocean for training until the war is over. The Island is unknown but before the war broke out it was checked and turns out the island is different nobody knows why. Turns out that island is Equestria (nobody knows about it) except one soldier of the United States Army. He name is Aiden.

This is a little bit crossover of homefront.
