  Approach March
  14-5. An approach march is the advance of a combat unit when direct contact with the enemy is
  intended. Units employ an approach march when they know the approximate location of enemy forces.
  Commanders task-organize units conducting an approach march before the march begins to allow them to
  transition to an on-order or be-prepared mission without making major organizational adjustments. For
  example, commanders direct artillery units to march in their supported unit’s columns, while engineer units
  are well forward to facilitate mobility. The approach march terminates in a march objective—such as an
  attack position, assembly area, assault position—or it can be used to transition to an attack. Reserve and
  follow and assume forces may also conduct an approach march forward of a LD. Figure 14-2 depicts an
  approach march.
