  battlefield. The amphibious landing force can be up to a detachment, operat-
  ing independently or with ground force units.
  13-91. In an offensive operation, tactical amphibious landing forces can seize
  bridges or road junctions near the coast and hold them until the arrival of the
  main land forces. Such landings can stop or delay enemy reinforcements or cut
  off his line of retreat. They may also help to maintain the tempo of the OPFOR
  ground forces’ advance, or they can be for deceptive purposes. Thus, landings that
  are tactical in scale may nevertheless have important operational repercussions.
  Reconnaissance and Sabotage Missions
  13-92. Reconnaissance and sabotage amphibious landings are in a special
  category. Seaborne raids may perform the multiple functions of
  • Conducting reconnaissance.
  • Damaging or destroying high-value installations located near a coast.
  • Disrupting the enemy’s C2 and/or logistics.
  • Tying down substantial numbers of enemy troops in the defense of
  long, vulnerable coastlines.
  Sea-delivered SPF teams may also perform deep reconnaissance and sabotage
  tasks of operational or strategic importance.
  COMMAND AND CONTROL
  13-93. In the administrative force structure, naval infantry forces are part of the
  Navy. However, they may conduct amphibious landings in support of an OSC or
  theater command as part of joint and combined arms operations. The SHC or
  theater command may allocate naval infantry units to an OSC in a given operation.
  13-94. Some amphibious landings are conducted by naval infantry delivered
  by naval transport, without support from or coordinated action with other ser-
  vices of the Armed Forces. In this case, a naval commander could exercise
  overall C2 of the amphibious operation.
  13-95. However, most landings by naval infantry are part of a larger joint
  operation or campaign in which they operate in conjunction with forces of other
  services. When sufficient naval infantry forces are not available, the amphibious
  landing force may consist of ground forces or SPF units that are transported by
  naval vessels. In these cases, the OSC or theater commander normally organizes
  and controls the amphibious operation, with expert advice from the chief of littoral
  warfare on his functional staff. The OSC or theater commander coordinates the
  joint actions of the naval and/or ground forces conducting the landing with support-
  ing actions by airborne, SPF, Air Force, and air defense forces. The commander of
  the naval transport unit and the commander of the transported unit usually share
  responsibility for overall control during loading, transport, and landing.
  13-96. The landing force commander is the commander of the naval infantry,
  ground force, or SPF unit forming the basis for the amphibious landing force.
  He is responsible for preparing and positioning his troops for embarkation on
  naval craft that will transport them to the shore. He must coordinate with the
  commander of the naval unit providing transport. After the landing, the land-
  ing force commander is solely responsible for conducting the operation. While
