  ways. (See ATP 3-21.18 for more information on the techniques and procedures for conducting dismounted
  movement.)
  Mounted Movement
  14-12. A mounted movement is the movement of troops and equipment by combat and tactical
  vehicles. Mounted movements are also called road marches. Armored and mechanized units routinely
  conduct mounted movements. The speed of the march and the increased supplies that can accompany the
  unit characterize this movement method. Armored and Stryker maneuver units are normally self-sufficient
  when conducting mounted movements over short distances. Infantry maneuver units cannot move themselves
  with organic truck assets and require assistance from transportation elements to conduct mounted
  movements. Considerations for mounted movements over extended distances include—
  * The ability of routes to support the numbers, sizes, and weights of the tactical and combat vehicles
  assigned to or supporting the moving unit.
  * Available refueling and maintenance sites and crew rest areas.
  * The need for recovery and evacuation assets.
  See ATP 4-16 for more information on route synchronization and movement planning.
  Air Movement
  14-13. Air movement is an air transport of units, personnel, supplies, and equipment including airdrops and
  air landings (JP 3-36). Units conduct air movements to move troops and equipment; to emplace systems; and
  to transport ammunition, fuel, and other high-value supplies through transport by helicopter and fixed wing
  aircraft. They may employ air movements as a substitute for ground tactical movements or to augment ground
  tactical movements. Air movements are generally faster than ground tactical movements and they can bypass
  ground threats. (See FM 3-04 for additional information concerning air movement.)
  Rail Movement
  14-14. Units use rail assets to conduct troop movement if they are available in an assigned area. Rail
  movements involve United States, partner nation, and local nation commercial trains. Rail movement can
  move a significant quantity of supplies and vehicles over extended distances on land quickly. Responsibility
  for coordinating the use of railroads resides in the Army Forces headquarters in the theater of operations.
  (See ATP 4-14 for additional information concerning rail movement.)
  Water Movement
  14-15. Water movements use vessels to transport equipment, supplies, and personnel. Water movement
  involves United States, partner nation and local nation commercial and military vessels. Water movements
  are slower than air movements, however they can move larger quantities of equipment and supplies and are
  more cost efficient than air movement. (See ATP 4-15 for additional information concerning water
  movement.)
  ORGANIZATION FOR TACTICAL TROOP MOVEMENTS
  14-16. There are several differences between the organization of troop movements. An approach march
  prioritizes security over speed while nontactical movement, tactical road march, and forced march prioritizes
  speed over security. A unit conducting an approach march employs larger security forces because of its
  greater chance for enemy contact. Units conducting approach marches arrange into combined arms
  organizations. An approach march allows units to disperse their task-organized forces into tactical formations
  without being constrained to existing roads and trails. A nontactical movement, tactical road march, or forced
  march can organize into columns for rapid movement. For example, vehicles of similar type, speed, and
  cross-country capabilities move together. Units conducting troop movements establish appropriate tactical
  intervals between vehicles. They also use fewer routes than units conducting approach marches.
