There is a leader so, you know if he looks at the left door when you enter the room, you are to look at the right door. Make sure your covered on all fronts.
If there is no leader, you risk two people looking into the same door, exposing yourself, leaving yourself vulnerable to an unexamined door.
Thats why we have leaders.
The best leaders though are above that rank. The next step, is that you are a symbol. Not even have to speak direction at that point.
