7-153. Bypass criteria should be clearly stated, and it depends on the mission variables. For example, an ABCT or SBCT commander in an open desert environment may direct that no mounted enemy force larger than a platoon can be bypassed and that all other forces will be cleared from the brigade axis of advance. Any force that bypasses an enemy unit must maintain contact with it until that force can hand that contact off to another friendly element, usually a force assigned a follow and support mission.
