This is my first story that I've written in almost a year, it is based on my unnamed science fiction universe, which I have decided to call Future Imperfect. Warning:This story contains violence and strong language.

Prologue
It was cold, metallic, colored in a dark grey with red stripes on the side. The engines of the freighter let out a eery crimson colored glow. The freighter was bulky, around 400 meters long. The hull was featureless, with the exception of the view ports around the bridge area, which had a sickly yellow tint to them which was common in Terran starships. A group of men moved around the cargo bays, opening up boxes containing weapons.
"Gentlemen, as you all know," Called out the leading officer, "a group thirteen of our fellow Rebels have been captured by the Confederates and are to be executed via firing squad. We need to take out the firing squad and free our brothers."
These were apart of a Rebel militia that was one of many hailing from the Outer Colonies. Around 20 years ago, the Outer Colonies had broken off from the Terran Confederacy after being under the totalitarian regime of Gildar De'Vires, Chancellor of the Confederacy, and the supreme dictator of Mankind who took power over 80 years ago.
An announcement came on the ship's intercom; "We are now exiting hyperspace and approaching Agreas IV."
The leading officer, Adam Lanskey loaded a shell into his shotgun and pumped it.

The surface of Agreas IV from space looked like it was covered in a large blanket of ash. The freighter, Valiant, entered the orbit of the planet and prepared to land. Flying across the rocky, ash colored surface, the Valiant approached the city of Cardon. The Valiant's landing gear popped out as is began to land. The Rebels concealed their weaponry underneath their clothing. They made their way to the Central Plaza.

The captured rebels stood in the middle of the plaza, lined up one by one, restrained with handcuffs. Across the from them was a firing squad of six Confederate soldiers. These soldiers were members of the most feared army in the known galaxy. The gas masks that allowed them to breathe on other worlds and to conceal their faces, blocked all expression, making them less human. Their great coats gently flapped in the breeze. Their commanding officer looked at the rebels,
"Traitors, under the orders of Chancellor De'Vires. You shall be executed for your treachery!", He turned to the firing squad, they aimed their assault rifles at the prisoners. "On the mark of three, fire!". The rebels began to feel an intense feeling of misery.
"One.......two.....thre.." Suddenly a bullet pierced the back of the officer's head. The Rebels jumped out of hiding, they began to fire upon the Confederate soldiers. The faded blue colored uniform of some of the soldiers were stained with blood. Several rebels ran to their restrained brothers, pulling out cutting devices to open up the arm restraints. As the last firing squad member fell to the ground, blood dripping out from the bullet hole in his helmet. With the captured rebels free, they began to make a run for the landing platform, hoping to reach the Valiant. Suddenly, the three wheeled bulk that is a Confederate APC rushed onto the square, it's back doors opened up, twelve Confederate soldiers jumped out and opened fire onto the fleeing rebels.
