One fireteam takes an overwatch position while the other team bounds (a bound is a 3–5 second rush) to a new covered position. This way there is always an overwatch team that can react instantaneously to enemy fire (the bounding team would have to stop, take cover, locate the enemy, and aim before they could return fire). Once the covered position is reached by the bounding team, they now assume overwatch positions while the other team then becomes the bounding team.
