SCP Lockdown (Thumbnail is bad I know)

Chapter 15: Ventilation Adventure

Name: MTF Commander, #### ###

So, we entered the ventilation systems, it was quite hard finding a hole, but we found one and they forced me to crawl in the vents. Now crawling my butt through the echoing and large vents trying to find an adrenaline filled Class-D. When I was in the control room before running off to the armory, I heard some people talking about MTF TAU-5, otherwise known as the Samsaras, these guys were the best of the best, they are cyborgs with immortality that wear the flesh of a dead god. 

I was trying to be as quiet as possible, trying not to alert the Class-D about my location. I started to hear thumping and bumping in the vents, he was near. I continued to crawl through a small, cramped, but large vent system until I saw a person crawling. I snuck behind him and tazed him.

    I heard him scream in pain and stop crawling. I crawled over to check up on him. He was unconscious. My head started to pound in agony, the now familiar ringing noise became louder as I held my head, it was unbearable. It started to ease but it still was hurting like hell.

BEEP

"All units be advised, there was a breach in the ventilation system at the entrance of the Site, assumed hostile, possible Chaos Insurgency inside of the Ventilation System,"

I heard that and realized I had to get out or I might get killed. THUMP, it jumped me and I held my sidearm. I was dragging this heavy person through a ventilation system whilst having to worry about the Chaos Insurgency.

    The Chaos Insurgency was a Insurgent group that is also secretive, made with a goal to destroy and dissolve the SCP Foundation.

CRACK CRACK CRACK

A few whistles blew past me, one of them scratching me. I turned around to see a not well armed insurgent with an AK in hand firing at me. He seemed young, but no matter, they wanted to cause the end of the SCP Foundation, which in hand, could cause the end of the world. I fired my side arm. CRACK, hitting his shoulder, he screamed and yelped in pain, I fired again. CRACK, this time, it was in his face. Killing him. I continued to crawl across the large vents trying to get out.

I report to Command.

"This is MTF Callsign Delta-0-1, Chaos Insurgency confirmed in the ventilation systems, requesting immediate reinforcements," I say.

"Copy that Delta-0-1, I am sending a local NTF group towards your location." Command replies.

I was crawling when I saw an exit, but there were some people there, "BLUE BLUE!" I yell, they look down into the vents, looking at me dead in the eye. They pointed their rifle at me, CRACK, I felt nothing, they were gone. I looked up, I touched my head, nothing, I continued crawling until I made it out. I placed the about 170lbs Class-D on my back and trudged to the other side of the hallway.

    I met up with Michael and his squad, I set the guy down and told them,

"Hey, I got the dude, although knocked out, I had to kill a Chaos Insurgent, the are sending an NTF squad,"

"A Nine Tailed Fox squad? I thought they were at Site-52?" said one of Michael's soldiers.

"They were, they arrived a while ago when the base called in a lockdown," I said.

We walked to the CON-E area, where we checked in, and walked towards CON-K. We had to contain SCP-106, otherwise it might cause havoc amongst the site. I was thinking, why the Chaos Insurgency now? How did they know that we we're in a lockdown? This is the most secretive site out there, how did they find it? I don't know, I want to get to the bottom of this. The only reasonable explanation would be... A mole, a spy if I must.
