  7-178. When ordered to move,the BCT disengages,then moves and occupies the next designated position.
  A part of the unit displaces directly to the rear when the order to begin the delay is received and occupies the
  next designated position. The rest of the unit maintains contact with the enemy between the first and second
  delay positions. As these elements pass through the second position,the forces on that position engage the
  enemy at the greatest effective range. When the BCT can no longer hold the position without becoming
  decisively engaged, it moves to the next successive position. When conducting a delay from successive
  positions, the BCT may retain a reserve if the division has none. The reserve will frequently be small and
  employed as a counterattacking force. It protects a threatened flank, secures vital rear areas, or provides
  overwatch fires to a withdrawing unit.
