Equestria is at the brink of war, and an old enemy has returned. Celestia, desesperate, casts a spell to bring an army of humans. Mytical warriors said to have existed in Equestria, but gone extinct after the last God War.
Will the 12th SS, 50th British and 3rd canadian be able to put aside their diferencies? Will they even assist a pony who dragged them away from their world? Or will they just be another problem to the many Equestria has?

PS: The number of soldiers and tanks are not the real ones.
Also most names will be made up too.
