  Seal Off the Objective
  5-140. Units should ensure insurgents can neither leave nor reinforce the objective. In many cases, this
  may be the decisive operation. Some considerations include—
  • All forces must understand and adhere to rules of engagement (ROE) and escalation of force
  (EOF) procedures.
  • Establish an outer cordon to block avenues of approach into the objective areas.
  • Support force provides initial overwatching fire for the assault force (can be aviation).
  • Use of aerial UAS or aviation support to maintain observation as needed.
  Assault the Objective
  5-141. Any insurgent element at or near the objective is overcome by surprise and violence of action.
  Some considerations include—
  • Time the assault as close as possible to the execution of the cordon.
  • Perform quick, violent, precise, and audacious actions that focus full combat power at the
  decisive point.
  • Breach rapidly—if possible, the breach should be the first overt action of the raid.
  • If fires are used, the support element either provides a heavy volume of fire or precision fires
  dictated by civil considerations. Fires must be closely controlled to ensure precision using
  FCMs, marking, and signaling. On order or as planned, fires are lifted and shifted to support
  the assault element by suppressing enemy fire from the objective.
  Secure the Objective
  5-142. Units secure the objective by detaining insurgents, controlling personnel on or near the objective,
  clearing the objective of other threats, conducting SE, and setting conditions that prevent insurgent fires
  from outside the objective.
  Withdraw
  5-143. As planned, the unit withdraws from the objective area. A support force may provide suppressive
  fires for withdrawal or provide escort away from the objective. Commanders consider use of stay behind
  measures or devices to monitor backfill of insurgents or population support for the insurgency. A raid in a
  COIN environment may modify phase five and withdraws at the discretion of the commander.
  AMBUSH
  5-144. An ambush is a form of attack by fire or other destructive means from concealed positions on a
  moving or temporarily halted enemy (FM 3-90). Ambush patrols are combat patrols with missions
  to establish and execute ambushes to harass or destroy insurgents or capture personnel and equipment. (For
  further information on ambush, see FM 3-21.8 and FM 3-21.10.) By eliminating insurgents, an ambush
  contributes to improving public order and safety, a key civil security subtask. It may be used
  in clear-hold-build operations or strike operations.
  TYPES
  5-145. The two types of ambushes follow:
  • A point ambush involves elements deployed to support the attack of a single killing zone.
  • An area ambush involves elements deployed as multiple, related, point ambushes.
  CATEGORIES
  5-146. Based on the amount of preparation time, ambushes can be hasty or deliberate.
  • A hasty ambush is an immediate action drill of a friendly force with little or no information on
  the insurgent force. The discovery of a nearby insurgent element, usually moving, provides a
