It has been several months since the disappearance of Twilight Sparkle..

One night, after watching her sister raise the Moon and set the heavens alight, Princess Celestia begins to bed down for the night, only to be interrupted by portal forming in her room. From out of the portal comes none other than Twilight Sparkle, garbed in strange armor.

Princess Celestia, along with Luna, Cadence, and Shining Armor, are overjoyed by the Element of Magic's return, but are justifiably curious as to where she had been and what she had been doing. And so, Twilight begins her tale. A tale of survival against impossible odds. A tale of a people fighting for the most basic right of all sentient beings. The right to exist.

The U.S Recon sniper, one of the most deadly and stealthy forces of nature on the planet. However, when one of these shadow warriors ends up in Equestria, how will he be able to adapt and survive in a new environment fulled with ponies, monsters, and even a splinter cell group of terrorist plotting an attack on Equestria. All while lurking in the shadows and becoming a lethal phantom. Only he is capable of stopping the extremists plan to cause utter chaos.

He controls the trigger of fate.

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?

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.

So...I am currently in the process of writing a different version of this story. Its gonna be a fair while before I post it, but it has the similar but heavily revamped plot written in a completely different style. So keep an eye out for that.

When a United States Army Ranger arrives in Equestria, the land is plauged by chaos, even the Royal guards cannot fight them off. Befriended by the mane six, the soldier is hired to help guard and fight for Equestria...

I remember noticing some grammar errors when reading this first time, unfortunately I'm too lazy to correct. If you guys'll comment on them, I'll fix 'em.

Sergeant Gary "Roach" Sanderson and Lieutenant Simon "Ghost" Riley of Task Force 141 are revived in Equestria after being K.I.A. on the Russian-Georgian border. A massive combined evil force threatens to destroy the nation, and now the two must defend the ponies. Is there more to their arrival though?
Crossover with Call of Duty: Modern Warfare. Takes place between episodes 12 and 13 of Season 3.

This story was granted to me by JWR832, since he was unable to continue it. So, as one of his editors, I will be taking over. I will be consulting with him often, and he will be helping me change it to his liking. For my own purposes, all cursing (other than a few British words) will be omitted. I'm sorry if you don't like this, but it's just the way I write. Thank you all for supporting him, and I hope I can do almost as good as he did. This fic was just too good to die.

Inkie Pie was, without any kind of doubt, the most influential musician that ever lived. Born on a rock farm, her strange life would serve as both inspiration and cause for her songs.

This is her story.

Lieutenant Rodger T. Laurence, a pilot in the United States Navy, had just taken off from the USS Wasp on a routine recon mission. Mid-flight, Rodger experienced an event that he could never have imagined. Miraculously, the stunned pilot finds himself in foreign skies with no way of contacting home, and is greeted by an unexpected inhabitant of this strange new land.

As long as there have been humans, people have disappeared without explanation; and as long as there has been militaries, there have been those who go missing. In 1986 I was one of those who vanished into the land of Equestria. At the time I was flying an F-14 Tomcat with the U.S. Navy's VF-84 fighter squadron. But life has a funny way of getting in the way of our plans and causes us to create new ones. My story was one of many. Along the way I got to know many famous people and help improve the nation of Equestria. I now write my story and hope you enjoy.

New side story here.

Terrorism, in the past century, has come to be one of the greatest threats to nations all over the world. It has always existed, and may always exist and threaten peace. Despite the danger, governments still bicker, as usual, and hamper any real attempt to counter it.

Officially, there is no multi-national effort to combat any and all terrorism. Unofficially, that organization is Rainbow. Consisting of the best soldiers from nations around the world and armed with the best equipment, this 'blacker than black' unit battles terrorists wherever and whenever; no matter who they are by any means necessary.

These men, who do not exist, receive no real credit for the battles they fight and the lives they save. That doesn't matter; even existing doesn't matter to them. They are dedicated to protecting innocents from an enemy who seems everywhere and nowhere, no matter where they are...
