  Patrol-Base Planning
  4-45. This refers to planning that occurs when the team receives a change of mission during the
  conduct of an operation. LRS patrol-base principles apply. The team--
  • Maintains security.
  • Plans and issues a FRAGO.
  • Plans resupply.
  • Plans for continuous communications.
  CONTINGENCY PLANS
  4-46. The contingency plan covers alternate, anticipated major events that could occur before, during,
  and after an operation, for example--
  • Replacement of team members as needed to fulfill mission requirements.
  • Transportation to the planning facility.
  • The planning facilities (garrison or field).
  • Direct support for unserviceable equipment.
  • Acquisition of mission-essential equipment.
  • Security during the mission planning process.
  • Reposition to COB, AOB or MSS.
  INFILTRATION PHASE AND INSERTION METHOD
  4-47. The infiltration phase extends from the point of embarkation to arrival in the objective area.
  Insertion method options include--
  • High altitude, high opening (HAHO).
  • High altitude, low opening (HALO).
  • FRIES.
  • SCUBA.
  • SPIES.
  • Air.
  • Vehicle.
  • Rubber boat.
  • Stay behind.
  • Rollover.
  • Foot movement.
  4-48. Any requested SEAD and CAS start when the insertion platform crosses the FLOT and starts
  moving towards the insertion point. Insertion normally ends after the team caches nonmission-essential
  equipment and the insertion platform leaves the loiter area. Generally, the infiltration phase continues
  with team movement from the point of insertion to the security halt, and ends before the objective rally
  point (ORP). Ideally, infiltration occurs during times of limited visibility. If the team must halt during
