Excerpt from a space war

What are these things anyway? Where do they come from? They're
extremely smart, and they are very quick I almost wish I wasn't here. I
almost wish I were back home with my father yelling and my mother
getting drunk staying out all night.
I thought that this would make me a man but I'm...I'm scared I'm scared
as hell. I came here to this place to protect others but these things
they just...keep comming and they don't have any wepons. They attack
and attack. When they jump on you they turn you on your stomach and rip
your back open with their claws taking out your spine for some kind of
trophy.
They almost seem to laugh as their blood soaked limbs
tear apart your flesh.
I know because I watched my partner die by one's hands. I couldn't stop
him he was too fast, and before I knew it they were everywhere. One of
them decended on us at first as we checked out a civilian site. We
recieved a report that some people were trapped there but when we got
there not a soul was to be found. It was dark and we heard noises, the
air was thick and hot we were ready for an attack but niether of us
were ready for what was next we heard metal being torn apart, glass
breaking and screams, unholy screams. We ran from the site to where our
"moblie defense unit" was waiting but we were too late. They had come
and gone leaving nothing but carnage for the eyes to see. Body parts
everywhre and the unit ripped apart like a tinfoil cover. Niether one
of us said it but we were kind of glad our lives were speared. I
checked the perimiter as best I could and my partner Steve contacted
the base for a pickup.
I turned my back and he made the call when he finished I heard him
choke on something as if he'd swallowed a bone or something.
I turned to see up close for the first time one tof these creatures. It
had to be nearly 10 feet tall and it was kneeling over Steve's body.
Steve screamed an inhuman sound as the creature begainto do it's work.
Scaly, boney and almost purring it took it's huge claw and dug into
Steve's back. Then it turned and saw me and I fired as quickly as
possible. It's skin took the shot and it stood upright like a human and
was about o lunge toward me when I shot it directly in the throat the
only soft spot on it's body. It fell. Then I remembered that these
things always come back to the kill and in the distance I heard the
growling.
I ran as fast as I could I ran for cover. The growling was getting
closer but they hadn't found me yet so I spotted another civilian site
and went in. I called again for help notifying them of my position and
situation. I secured the area. The lower level had amunition thank god
because from what I heard there would be alot more of these things. I
blocked off the blind spots and waited for the calvery to come and
that's how I got here. Thinking about my parents.
I can hear the growling as they search for me they're getting closer. I
hear the units searching for me too and they're getting closer. I guess
it's just a matter of who gets here first. I hope the units find me
first. I hope the units find me first.
