Ripped The Fuck Apart

Thousands upon thousands of sickly green creatures hobbled over the hills, heading towards us. All two hundred and ninety-nine of us cocked our guns.
They came closer and closer, their feet thundering against the ground.
We aimed.
I thought about my wife who was taken from me last night, who was supposed to be fighting along side us tonight.
"KILL THEM ALL!"
I shouted so hard, I choked the last word with small bits of flesh blood.
The battlefield lit with our fire. We mowed those disgusting bastards down, but they still kept coming.
"Keep them back until the drivers show up," one of the commanders shouted.
I watched them fall, turn into thin, green smoke, floating away until one of their comrades inhaled them, eyes glowing.
They flooded the field before us. There were more and more and more and more. Their pack came closer and closer to us. A raging stampede, like a tidal wave, so much larger then us. I could feel fear creeping up my spine, trying to make it's way into my mind and seizing my body. I forced myself to think of my wife's violated and mutilated body, and I felt the icy fear melt away to white-hot rage.
We kept firing for what felt like hours, for what was most likely five minutes.
Finally, we could see the drivers, floating on top of the bastards. Wraiths. Wraiths were driving the pack, as dogs would drive a herd of sheep. The shrouded figures danced in the air, wiping and striking at the sluagh with their sharp claws and their long tongues.
"Wraiths!" Someone shouted.
"Take 'em down!"
We all let go a cry so loud, I swore I could see the wraiths tremble. We charged directly into the sea of monsters, firing and screaming.
Most of the sluagh moved out of our way, but there was too many of them for them to all move. So I shot at their legs, making them fall down. I climbed on top of their flailing bodies, running toward the wraith near me. I jumped from the head of a sluagh and struck the wraith with the butt of my gun. It came crashing down with me onto the sluagh, and I was nearly trampled. I got up and found the wraith floating inches from me. I shoved my gun into it's hood, and pulled the trigger. Immediately after it dissipated, I could see the nearby sluagh disperse.
We continued to take down the wraiths, fighting our way through the thick crowd, mowing them down as we went.
The pack continued to disperse in wild directions. We were fucking them up. We were winning. When the pack had almost completely gone, I saw one last wraith, floating left and right, distraught and frantic. I walked up to it, and it turned to me. It turned back to try and get away, but I had grabbed the tails of it's shroud and pulled it back towards me, slamming it to the ground. I brought my gun up, and struck the back of it's head with the butt of my gun. I raised my gun again, and brought it down hard. And again, and again, and again, relishing every shriek it made. Finally, it dissipated into green smoke.
I stood up and saw all the soldiers staring at me. I slung my gun over my shoulder and walked away. I prayed to whatever fucked up god there was that under a large, star light sky, my wife was waiting for me when my time was up.
