The door swings quickly open. "What's that?" yells a startled voice from within the room. Pressed low to the wall outside the room, you don't utter a sound. You don't even dare breathe. You are as silent as death itself and with good reason - you are death, a locked-and-loaded destroyer of evil men and plans. Silently you detach a flash-bang grenade. The pin is pulled and you toss it into the room. Look away! You need your sight. It's the terrorists you want to blind. BAM! The nasty firecracker has done its work. You swing the M4 Carbine into position and hit the room. It's time to kill or be killed.
