  6-112. The commander assigns, as a minimum, an area of operations to every maneuver unit, a line of
  departure or a line of contact, a time of the attack or a time of assault, a PL, an objective, and a limit of
  advance to control and synchronize the attack. (See figure 6-9on page 6-28.) The commander can use a battle
  handover line instead of a limit of advance if the commanderknows where to commit a follow-and-assume
  force. The commander designates the limit of advance beyond the enemy’s main defensive position. If the
  operation results in opportunities to exploit success and pursue a beaten enemy, the commander adjusts
  existing boundaries to accommodate the new situation. (SeeFM 3-90-1 for additional information.)
