Previous: 5-14: Graphic Control Measures
5-15. Tactical road marches are employed using three tactical march techniques: open column, close column, and infiltration. Each of these techniques uses scheduled halts to control and sustain the road march. METT-TC requires adjustments in the standard distances between vehicles and dismounts.
5-16. During movement, elements within a column may encounter many different types of routes and obstacles simultaneously. Consequently, parts of the column may be moving at different speeds, which can produce an undesirable accordion-like effect. The movement order establishes the order of march, rate of march, interval or time gaps between units, column gap, and maximum catch-up speed. Unless the commander directs them not to do so for security reasons, march units report when they have crossed each control measure. Throughout the move, air and ground security are maintained.
