  * Current data on traffic regulations and control restrictions, obstructions, detours, defiles,
  capacities, surface conditions, and enemy activities that affect the highway net.
  14-49. The provost marshal prepares a traffic control plan from information contained in the traffic
  circulation plan. The traffic control plan is normally prepared in the form of an overlay. Units use available
  aviation elements, movement regulating teams, and military police units to assist in traffic control, but they
  can assign this mission to other elements, such as battalion scout platoons.
  PREPARING A TROOP MOVEMENT
  14-50. Reconnaissance precedes unit movement. Before a unit starts any march, a reconnaissance element
  from that unit reconnoiters the route from its current location to the SP and determines how long it will take
  the unit to reach the SP. This reconnaissance element continues beyond the SP and carefully examines the
  route’s trafficability, including the impact of weather, road surfaces, and terrain and civil considerations, such
  as local nation use. This reconnaissance also includes alternative routes and choke points, such as defiles,
  bridges, and fords, which could slow the march. This reconnaissance element complements map and technical
  reconnaissance and provides units with important information about the terrain, obstacles, and potential
  enemy forces in the area. Units then establish TCPs at critical locations or mark important information to
  avoid confusion.
  14-51. A quartering party often accompanies reconnaissance elements to mark routes and BPs. The
  quartering party may also secure new positions with observation posts or limited forces until the unit
  conducting the movement arrives.
  14-52. The unit begins a tactical movement, such as an approach march, fully supplied. The unit refuels at
  every opportunity, such as at halts and on arrival at the final destination. The transportation of fuel and the
  security of existing stockpiles are major factors in any mounted movement. Commanders may choose to
  conduct a refuel on the move to extend the range of the unit’s vehicles. Refuel on the move is a technique
  where units position tankers just off the route to refuel vehicles rapidly. Such refueling provides only
  established quantities necessary to extend the vehicles’ range to the desired distance. The type and method
  of movement selected will determine the need for pre-positioned sustainment assets to conduct rapid and
  efficient refueling and resupply.
  EXECUTING A TROOP MOVEMENT
  14-53. A unit’s ability to move depends on its march discipline and ability to maintain required movement
  standards and procedures as prescribed by its movement SOP and movement order. This includes staying on
  the route and maintaining start, passage, and clear times. March discipline is essential throughout the
  movement. Any deviation from the movement order may interfere with the movements of other units and
  may have serious consequences. However, march discipline can only be maintained with established
  movement control.
  14-54. Movement control is the dual process of committing allocated transportation assets and regulating
  movements according to command priorities to synchronize distribution flow over lines of communications
  to sustain land forces (ADP 4-0). It is on a continuum involving coordinating and integrating logistics,
  movement information, and programs that span all the levels of warfare. The balancing of requirements
  against capabilities and assigning resources based on the commander’s priorities guide the conduct of
  movement control. Movement control gives commanders the ability to deconflict the movement of units—
  troop movement—and the distribution of supplies and services inherent in sustainment.
  14-55. Units may not move across boundaries into another unit’s assigned area without receiving clearance
  from the owning unit. The designation, maintenance, route security, and control of movement along routes
  in an assigned area are the responsibility of the owning unit unless the higher echelon’s coordinating
  instructions direct otherwise. An example is when one or more routes are reserved for the exclusive use of a
  combined arms battalion operating forward of a BCT as a guard force. (See ATP 4-16 for a more information
  on movement control and the establishment of route synchronization measures.)
  14-56. The strength and composition of the moving unit’s security elements vary depending on the mission
  variables. Units employ organic assets and supporting security assets to protect forces from enemy activities.
