At the dawn of the discovery of a new sentient race, the United Nations must answer a call to arms after the peaceful society of Equestria is threatened by an enemy unknown to humans. It will take guts, courage, and sacrifice to overcome the long road ahead. Forged in the fires of conflict, a true soldiers bond will be formed between the two races. A true sense of camaraderie.

It has been nearly sixty years since humanity witnessed the devastation of a World War, or any other kind of large-scale conflict. Equestria's abstinence has been even longer, with battles that rage across the entire land not being seen for centuries. Though both have seen their share of small-scale skirmishes, a duel of total annihilation across a large scale has been avoided by both sides time and again.

But peace is never lasting. For both sides, it lies on a cliff, requiring only one good push to send the participants into a plunge of death. Equestria's unexpected appearance may turn into that final push, as alliances, deception, and distrust threaten to launch a conflict that will lead both worlds to utter ruin.

Spartans never die, they're just missing in action. This has never been more true for Jorge-052 as, after activating the slipspace drive that was supposed to kill him, he is instead flung into a strange world where war is but a distant memory. Will the aging soldier be able to adapt to this new peaceful planet? Or will his only salvation be found in finding a way back to his own chaotic universe?

Now featuring a TVTropes page by Sabo88

SGT Jennings dropped into New Mombasa to take over a Covenant cruiser. When a lucky Anti-Aircraft shot takes away his ability to control his pod, he careens end-over-end into a slipspace portal, and emerges in Equestria.

Be warned, there is more cursing in the beginning then there will be later, due to an all-military environment in the beginning.

(STORY IS UNDERGOING REEDITING)
“Demonstrate to the world, there is ‘No Better Friend, No Worse Enemy’ than a U.S. Marine.”
~Gen. James Mattis

Excited for his first deployment, young marine LCpl. Kevin Brooke and his fellow squad mates of Bravo Company 2nd Battalion 1st Marines, begin their journey through the Pacific Ocean with the U.S. Navy carrier fleet. On their second day of voyage, they encounter a large floating crystal, ending in a swift and devastating battle.

After awakening in an unknown world, four ships (‘USS’ Anchorage, Princeton, Spruance & Michael Murphy) must adapt to a land filled with talking ponies while finding their way back home. However, during their stay, Queen Chrysalis rebuilds her army to take on her new enemies, and Brooke slowly unfolds the depths of a forgotten past.
