  Insertion and Extraction Methods
  The LRS team must be prepared to insert and extract by various means to accomplish
  their mission. The team can insert and extract by water (Section I), air (Section II),
  land (vehicle [Section III] or on foot [Section IV]); or it can stay behind [also covered
  in Section IV]. Proficiency at inserting and extracting improves the team’s likelihood
  of accomplishing—and surviving—the mission.
  A member of the LRSU headquarters should accompany LRS teams on insertions and
  extractions by air. The presence of a representative from headquarters emphasizes the
  criticality of the air mission. He can also assist with navigation and other key duties,
  as dictated by the unit SOP.
  Section I. WATERBORNE OPERATIONS
  Using inland and coastal waterways can improve the speed, stealth, and flexibility of a LRS team's insertion
  and extraction.
  CONSIDERATIONS
  5-1. Waterborne insertion means include using surface craft, swimming on the surface, helocasting, or
  a combination of these. Whichever they choose, they should execute during limited visibility for
  maximum stealth. While planning waterborne operations, leaders must consider the following factors:
  • Enemy situation.
  • Civilian situation.
  • Shipping.
  • Beach landing site, which must allow the team to infiltrate and support movement to the inland
  objective.
  • Environmental factors; for example, winds, waves, fog, thunderstorms and lightning.
  • Equipment.
  • Time schedule. Leaders use reverse planning to schedule operational events.
  • Drop site. The team debarks a larger vessel at a planned drop site then begins infiltration.
  • Launch point. A point where swimmers enter the water and begin infiltration.
  • Method of loading. Supervisors inspect to ensure loads and lashings, especially waterproofing,
  adhere to unit SOP.
  COMBAT RUBBER RAIDING RECONNAISSANCE CRAFT
  5-2. Most LRS teams use a combat rubber raiding reconnaissance craft, commonly called a "rubber
  boat," for small-boat operations.
  TECHNICAL INFORMATION
  5-3. Specifications and other information about the rubber boat follow:
  Inflation—This boat is inflated with foot pumps, using four separate valves on the inside of the
  gunwale. Each valve is used to section off the rubber boat into five separate air-tight
  compartments.
