The creature shrieked, flinging blood, vomit and other body excrement across Van’s kevlar.  He stood there shocked at the gruesomely horrifying site, paralyzed with disbelief and fear.  The creature shrunk down and leaped onto the right wall and began crawling speedily towards him.  Van began backing up franticly, not able to turn his back on the creature.  When it was about three feet away from him, the creature leaped from the wall towards him.  Van fell back in fear screaming and holding the trigger of his MP5A4 swinging it in an upward motion.  The creature hadn’t fully reached him before his body was ripped in two by the upward spray of bullets.  The two pieces of body slapped the sides of the wall and flew past him.  Entrails and blood splattered his combat suit before the two pieces of body had reached the ground.
