Submarines can operate covertly close to hostile coastlines and insert small groups of special operations forces ashore. These special forces, with great secrecy and surprise, can support amphibious assaults, gunfire spotting, forward air control, tactical intelligence, sabotage, and insurgency operations. Submarines can also extract military forces and non-combatants.
Before and after inserting special operations forces, submarines can collect tactical intelliegence, perform coastal reconnaissance, and conduct strikes ashore with the Tomahawk cruise missile.
