Though Greg dispatched of the stragglers with relative ease, he sighed with exasperation when he knocked on the door and asked for entry like someone in major need of the bathroom. "We reached our destination quietly and safely. But if they're firing, they're still fighting... And we can't keep our heads down while men who depend on us are at risk now can we? we've got no time to dick around waiting for them to answer a knock." The colonel said sternly, though there was no hostility in his tone. "Hostiles are going to be coming from all sides, we need to get in there and get them out now." The colonel finished as he sheathed his entrenching tool. He drew his pistol from the holster on his chest and fired three quick rounds into the door and lock assembly. With practiced precision, he brought his foot up and slammed it against the door just under the bullet-holes. With a sharp crack, and the soft whine of thin twisting metal the door flew open. 

"This is combat now soldier, we get our men and get the fuck out." Carter exclaimed as he moved into the building, pistol raised. The first room was void of undead. Rows of washing machines and several baskets of forgotten clothing and laundry supplies were all that the room had to offer. With a single wave of his left hand, Carter gestured for Greg to follow, never lowering his weapon. "Clear. Let's move." Expecting Greg to follow suit and cover his rear, he didn't bother looking back at the captain unless the other had something to say or made a worrying sound. The colonel started into the hallway, slowly making his way toward the front lobby where the gun shots seemed to originate. As he searched, the officer spoke aloud, hoping anyone within ear shot would come to them. "This is colonel carter of the U.S. Military. We heard your gunshots and we've come to get you out of here. This place is going to be swarming with those things within a matter of minutes, we NEED to get out of here."
