Alexander, completely oblivious to what is going on inside of the dugout, continues to fight, keeping the Chinese soldiers away from the frontline. One by one, the soldiers fall at his hands, until, click! He pulls the dual drum magazine out of is M8A2, and tosses it to the side. He takes another magazine from the tactical bandoleer that spans across his chest and backside. He stuffs the magazine into the magwell of his rifle, pulling the charging handle back to ensure that the magazine is locked inside the weapon, and lets the slide shut. He aims down his sights, preparing to fire again before dirt kicks up in his face, the sounds of bullets ricocheting off of small stones in the dirt can be heard and he ducks down, dirt falling on top of him as several 7.62 machine gun rounds continue to pound the trench. They finally stop, and all that can be heard is a man above yelling, "Shǒuliúdàn!" and a small, round object drops into the trench next to Shock, and at that moment, his entire life flashed before his eyes, and he scrambled away from it as fast as he could. Luckily, the grenade went off just as he is outside of the radius, dirt, fire, and smoke consuming the area. His ears ring, and he tumbles into the dugout. He brings his hands up to his ears as though it would help stop the ringing, but realizing it won't, he brings them back down around his rifle.... but something piqued his interest, a slight liquid feeling on the grips of his M8A2. He examines his hands, finding the crimson, red stains of blood. His ears had begun to bleed, as well as several other parts of his body, however he was not aware. The pain in his ears set in, and he screamed, squirming up against the wall of the dugout, sharp pains everywhere in his body, a stabbing pain in his chest. He didn't know what was going on, but any veteran of war would have known that shrapnel from the grenade had pierced his clothing and ripped through his flesh.
EDIT: Wow it looked like a lot less when I was typing it :O
