Behind The Shield

You run up toward the front door with Charles. Charles pulls out the bullet shield and kicks in the door. You both file in single file, aiming your MP5's at anything that moves. Suddenly you see a man up in the cat's walk. HE FIRES AT CHARLES! You have known Charles since preschool and he is your best friend. The bullet leaves the gun and is heading toward Charles! WHAT DO YOU DO, FAST!
