A long time ago in a galaxy far far away

Chapter 1,Retaliation

It was war. The once slave system of Mindoir started using slaves and slave owners as soldiers and formed an army. The Empire quickly noticed and demanded the army be shut down immediately. Mindoir Refused and instead attacked the base Alpha 3948. The Empire refused to let this go unpunished and sent the 356th Army battalion and the charlie 4000 Star destroyer. Then the Empire landed about 2000 other battalions across the planet. Attacks on Mindorian bases under construction stopped the construction and turned it into debris piles. 10000 ships (an entire fleet) went down to the planet and made swift attacks losing no ships, yet over a hundred bases were completely destroyed. The first target the Empire had was the Mindoirian communication towers,then the Mindoirian power plants. All with OS(orbital strike). On one attack, A base was producing WMDs. The Empire decided to Send the 324th Army battalion to demolish it. On December 7 the battalion assaulted the base

Chapter 2,Assault

The battalion was a mile away,just watching the base and the weapons and soldiers everywhere. Commander Sank was afraid they would detonate one of the WMDs just to kill that one battalion. regardless he kept watch. They were told to only to attack when a vehicle was transporting something. At 1300 hours, the battalion saw a vehicle exiting the base. Quickly, a rocket trooper got ready and fired the rocket. BOOOM. The vehicle blew up and continuous gunfire followed. The battalion started moving forward, along with cover from above. Enemy sniper fire started killing the battalion and pushing them back. Thankfully, sniper turrets on board the Star Destroyer killed every single sniper, but by the time they were all dead only 900 men remained. The battalion moved in to the base and began looking for the generator. unfortunately,only 850 men out of 1000 men remained. Commander Sank, Captain Red, and Private Eagle were the wisest men in the Battalion,and they were the only ones with the guts to stay back with the Imperial WMD that they were getting to blow up the base.

Chapter 3, WMD escape

The attack waged, men falling, gunfire everywhere, Shouts and screams all around, The commander shouting orders, men dying to follow them. OS strikes were everywhere, explosions everywhere followed by flying slaves and owners. While the gunfire,explosions,and screams continued Eagle said "Commander, This is a suicide mission, We have to get out of here." The commander replied "I know Private, not like we can do much now can we." "Damn it" Eagle shouts as he turns and continues fire. The fire is getting stronger, men falling faster. within 1 hour of the attack only 500/1000 men remained. Then, A ship contacted all Imperial troops in the area "Damn,one truck got away,I repeat, one truck is getting away,in pursuit, all forces be advised scans show a WMD inside the truck, I repeat, A WMD in the truck. If any forces have visual, advised to open fire." The commander said " Eagle take 5 rocket troopers and go to the edge, he's doing circle, take point and take down the truck. Understood?" Eagle replied "Sir Yes Sir." and began to run to the Eastern side of the building. When he arrived, the truck was almost there. Eagle strategically placed all the troopers where the truck couldn't see them. Approximately 35 seconds later the truck ran through. Five rockets fired,Boom,Boom,Boom,Boom,Boom. All the rockets hit the truck and blew it to bits. "commander Mission Accomplished I repeat, Mission Accomplished, truck destroyed."
After the truck was destroyed, the battalion pushed through and made it to generators main entrance, the engineers destroyed the door and got inside. Even though they had made it to the Generator with 150 men, Every single man knew this wasn't the end.

Try focusing on making your chapters more detailed, or otherwise you could just have posted everything you wrote so far into one post.

Chapter 5, Endgame

Gunfire was chasing Eagle and the commander. While after while they turned abruptly to get some good shots at the fatal spots on their enemies, Eagle more than the commander. As they fired enemies fell, others crouching to help others and getting a shot themselves. It was gruesome. After both men had run 6.5 klicks, the Commander said "Private, get that trigger ready for when we pass 7 Klicks you can blow this place into Nuclear dust." ordered the commander. "Sir yes Sir" replied Eagle. They continued to run turning to shoot, running backwards to shoot. After a while a system in Eagle's helmet indicated that they were over 7 klicks away from the base. " Sir, we just passed 7 klicks" Shouted Eagle to the commander waiting for the response he had wanted. " Very good Private, Permission to blow it." Replied the commander. " Sir yes Si..." A laser was heard right at the moment Eagle fell. They had shot him in the leg. Approximately 3 seconds after he fell, BOOOOOOOOOM the base blew up behind them. Debris began to fall every where. Eagle was able to stand and see his commander with a pole through his throat. 10 seconds after he finished standing up, A pole went right through his stomach. Thankfully once he was taken to the medical stations he survived. After the war ended 2 weeks later when they were overrun, He was reestablished as a private in the 368 Army battalion.
