  14-6. Based on the products of the IPB process, the overall commander assigns an area or an axis of advance
  in combination with routes to a unit conducting an approach march. These routes, assigned areas, or axes
  facilitate the force’s movement and maximize its use of concealment. Commanders assign the force
  conducting the main effort and forces conducting each supporting effort separate routes, assigned areas, or
  axes of advance unless an individual subordinate unit has the task of either follow and assume or follow and
  support.
  14-7. As the approach march nears areas of likely enemy interference, commanders divide their unit’s main
  body into smaller, less vulnerable columns that move on additional multiple routes or cross country while
  continuing to employ security elements. They take advantage of successful reconnaissance and security
  operations to increase the distance traveled before the main body begins to maneuver. As discussed in Chapter
  13, the advance and any flank guards remain within supporting distance of the main body, which stays in
  these smaller columns to conceal their movement.
  Forced March
  14-8. A forced march is a march longer or faster than usual or in adverse conditions. Forced marches
  require speed, exertion, and an increase in the number of hours marched each day beyond normal standards.
  Soldiers cannot sustain forced marches for more than a short period. In a forced march, a unit may not halt
  as often or for as long as recommended for maintenance, rest, feeding, and fuel. Units must understand that
  immediately following a long and fast march, Soldiers and combat vehicles experience a temporary
  deterioration in their physical condition. The combat effectiveness and cohesion of the unit also temporarily
  decreases. The plan must accommodate stragglers and address increased maintenance failures.
  Tactical Road March
  14-9. A tactical road march is a rapid movement used to relocate units within an assigned area to
  prepare for combat operations. The primary consideration of the tactical road march is rapid movement.
  Typically, a unit executes a tactical road march using the mounted method of troop movement. Based on the
  mission variables a unit can execute a dismounted tactical road march. However, the moving force employs
  security measures, even when contact with enemy ground forces is not expected. Units conducting tactical
  road marches may or may not be organized into combined arms formation. For example, a forward support
  company providing supplies to its supported maneuver companies can execute a tactical road march. During
  a tactical road march, the commander is always prepared to take immediate action if the enemy attacks.
  METHODS OF TROOP MOVEMENTS
  14-10. There are five methods of troop movements that units can execute. These methods are—
  * Dismounted movement (foot marches).
  * Mounted movement (road marches).
  * Air movement.
  * Rail movement.
  * Water movement.
  Generally, units can execute these methods in combination. For example, a unit can initially execute a
  mounted movement and then transition to a dismounted movement. Additionally, each method can be applied
  to nontactical or tactical movement.
  Dismounted Movement
  14-11. A dismounted movement is a movement of troops and equipment mainly by foot, with limited
  support by vehicles. Dismounted movements are also called foot marches. Dismounted movements increase
  units’ maneuver options. Their positive characteristics include combat readiness (because all Soldiers can
  immediately respond to enemy attack without the need to dismount), ease of control, adaptability to terrain,
  and independence from the existing road network. Their limitations include a slow movement rate and
  increased personnel fatigue. A unit conducts a dismounted movement when the situation requires stealth, the
  distance to travel is short, transportation or fuel is limited, or the situation or terrain precludes moving other
