  CONTROL MEASURES FOR A PURSUIT
  7-14. Pursuit control measures should be flexible and allow adjustments to reflect changing conditions. Units
  use control measures in the pursuit to—
  * Retain tactical options to converge on the most important axis or to redirect the pursuit effort on
  a new axis.
  * Provide subordinate units as much freedom of action as possible, consistent with security and
  maintenance of command integrity.
  * Provide units the flexibility to engage enemy reserves or counterattack forces.
  * Prevent fratricide.
  7-15. Commanders employ centralized planning and decentralized execution during a pursuit. They balance
  the need to prevent fratricide and friendly fire incidents with the need to allow subordinates to take advantage
  of fleeting opportunities in a pursuit with rapidly moving forces and an evolving situation. Commanders
  designate assigned areas for each maneuver unit involved in the pursuit. During a pursuit, they establish few
  control measures for the direct pressure force other than phase lines, checkpoints, and some fire control
  measures such as a restrictive fire line. Units use phase lines to designate a forward and rearward boundary
  for the direct pressure force. The forward boundary relieves the direct pressure force of any responsibility
  beyond the forward boundary. It also gives the higher echelon headquarters flexibility to coordinate with the
