No Matter what you do, you need someone to play an "anchor" you have a point man, but an anchor will be in the back, yelling directions, laying cover and telling everyone what he sees. He is generally far enough away from the other team that he doesn't need to stay so well concealed. That way he can just yell out any movement he sees, how many are left and so forth...
Helps keep the team organized and moving.
