This story is undergoing a massive rewrite. Expect everything to change soon.

A Russian MVD Spetsnaz team is sent smashing into the ground after the Mil Mi-24 they were in was knocked out of the air. A short time later, the crew and passengers wake up to find themselves in the wreck of the helicopter - but nowhere near Moscow.

As they desperately attempt to find out where they are, they will discover that they are not alone: Other humans have also found themselves in similar situations. However, these disorganized forces may soon be fighting for their survival, against an enemy that they could never have planned for...

The original version of the story, as published 2013-2015, can be found here for those that want to read it as it was. Editing on the original story was done by The Rainbow Brony, and I am thankful for the time that he put into the story to make it better than it would have been otherwise.

(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.

My Little Pony: Friendship is Magic created by Lauren Faust and owned by Hasbro.
Ace Combat owned by Namco

It's been two years since representatives of the United Human Federation arrived in Equestria, begging for help in a crisis situation. Months later, the Human-Equestrian Alliance was formed. But now, relations between the two species are strained, as mistrust begins to boil. It comes to a head when all UHF forces leave Equestria during a massive invasion, leaving the ponies to fight for themselves. Have the Humans abandoned their allies? Or do they have something bigger up their sleeves? The clock is ticking, as the ponies are on the verge of complete surrender, and humanity might just be Equestria's last hope.

(A/N: I know this is a beaten to death idea, but I'm putting my own spin on it, as well as some "Ace Combat" Elements.)

Equestrian Military Unit File
TOP SECRET

Unit: 1st Special Operations Group
Sub-units: 1st Tactical Fighter Squadron 'Starbirds'
1st Armoured Company 'Steel Strikers'
1st Special Operations Platoon 'Ghosts'

Unit overview: The 1st SOG is a elite special forces unit that uses extremely advanced weaponry and tactics to accomplish operations that regular units would find nearly impossible. It is split into four sub-units that often operate independently from each other, though often lending support to the others. An interesting fact worth mention is that the unit's equipment, as well as half the personnel, are of alien origins. They call themselves 'humans', and all became ponies upon arrival in Equestria, which they claim is a complete accident. After arrival, they eventually became part of the Equestrian military, and have trained ponies to use their surplus equipment becoming the 1st SOG. Since their inception, they have distinguished themselves, successfully eliminating two rampaging dragons and three hydras.
