Although it didn't seem like they engaged the targets fast enough when entering the room, it is good training and a few more practice runs will make them a lot better.
Watch the first guy into the room, he walks into the room and actually looks down for his mark to stand on. They all seemed to wait for each other to get on their mark before firing. I know safety plays a roll but.....and why is the pointman only have a pistol, I would have had a shotty up front leading the charge.
