The kids had balls at least. York was pretty sure he was going to hell for thinking that but here they were, chasing down a monster that had made short work of werewolves. Hell probably wasn't too far off from this place. York just positioned his weapon and followed Wash, behind him but to the side so that his partner was in his blindspot. Some liabilities you learned to adapt to.
The creature didn't give anything away, nearly impossible to see, so it was a good thing they had their full body armor. At the mention of a human, York instinctively swiveled his gun in the direction of nine o'clock. Wash needed him though and the creature was more important so he turned his gun back to the fight at hand and laid down cover fire. It all happened in seconds.
"Yo!" he called to the kids over the sound of gunfire, "9 o'clock. Go." He jerked his head in the direction he wanted them to go. "Capture not kill," he added as he laid down more fire. Your bullets do not appear to be making a difference Delta observed, sharing the communication between him and Wash. "Tell me something I don't know," York muttered. He tried to focus on joints or it's underside, but anytime he stopped to reposition, the creature advanced.
