Just a short little snipit.
We are Sigma Squad
Within minutes of being called Sigma Squad the elite of the elite Enclave soldiers assembled in the lower level of the mobile base crawler. The members of the squad stood at attention as Sigma Leader in his Hellfire Armor spoke.

"Men, this is a grave day. at 0600 The Brotherhood of Steel began an assault on the outer perimeter, but that is not why I called you here."

The squad made no movement, or said a single word. They were the a poster of discipline.
"At 0630, the Lone Wanderer was spotted emerging from the Presidential Metro." Sigma Leaders voice was grim, it was always grim but today it was noticeably worse.
"But Sir, that's inconceivable, the place is overrun by reavers, and the train doesn't even work." One of the squadron said.

"Well he found a way" Sigma leader took a deep breath. "I won't lie to you men, nor spread any propaganda, everyone who has ever faced the lone wanderer, anyone who has stood there ground against him has died, but where they failed we will succeed for we are Sigma Squad"
His squad cheered at this words and he paused briefly and looked over the men he had trained and worked with for many years. They were squad-mates, friends, family.
"Before us stands the degenerate wasteland horde, but have no fear, for we are sigma squad the elite of the elite. The best that the pure humanity, the true humanity has to offer. once their champion lies broken at our feet the brotherhood will fall and at long last the pure humanity will rise again!" His squad cheered again.

"For Eden, for the enclave, for the last best hope for pure humanity we shall be victorious"

A sniffle came from the corner. "That was beautiful" Sigma Squad turned to see the devil himself, "The Lone Wanderer" before they could fire a shot the nuka grenade was in the air, it exploded in a firey blast and Sigma Squad was no more.

From around the corner behind LW stepped a woman with bleached white hair, half of which was shaved off, she wore a metal collar around her neck.
"What were you waiting for lover?" Clover asked

The Lone Wanderer just shrugged, "His speech was just so inspiring, I thought the least I could do was let him finish it before I killed them"

"That's cold lover"

"I don't know" he said as he put his arm around her shoulder to lead her onwards.
"I thought it was a nice thing to do"
Clover simply glared at his hand, "I thought I told you I didn't like that"
The Lone Wander just sighed, "Alright have it your way" he moved his hand from her shoulder to her rear.
"Thanks lover"

Sigma squad seemed like something epic until one man infiltrated their base and turned them all to ash in a second...And then turned unto a bunch of experienced rookies. I assume this was short little comedic entry, cause I snorted a little. Still a couple grammatical errors including missing commas and other stuff. Remember to put a comma at the end of a piece of dialogue if your going to be denoting who says it and instead of putting *sniffle* like it's some kind of script why don't you put "a sniffle came from the corner" or something like that. I know that this is a short little sketch, but still...

Anyway, good job. Made me chuckle so I hope you achieved your goal, until next time...

Thanks for the input and advice, but yeah you got the basic idea it was meant to be comedy. Show the pride, glory the Enclave feels. Then kill them in the most humiliating way possible. At least none of them suffered the shaddy sands shuffle.
Maybe the grenade should have had a message on it, like "Goodbye"
