Actionbeaches is exercised through a Navycontrol group. Organization of thecontrol group is based on the arrangementand number of beaches on which the LFis to land.See NWP 3-02.2, Ship-to-ShoreMovement, for detailed discussion of theorganization and functions of the Navycontrol group.• VTOL aircraft units employed in theship-to-shore movement are subordinateelements of the LF. These units executethe ship-to-shore movement inaccordance with the landing plan. Plansinclude provisions for shifting control ofVTOL aircraft operations to the CLFwhen the situation ashore permits.During the ship-to-shore movement,the CATF coordinates and controls airoperations through the Navy TACC(afloat). Within the TACC (afloat),coordination of VTOL aircraft operationsis accomplished by the helicopter/VTOLaircraft coordination section. Control ofVTOL aircraft ship-to-shore movementis further delegated to the HDC, whichis the primary direct control agency forthe helicopter/VTOL aircraft transportunit. Once established ashore, the CLFcoordinates and controls air operationsthrough the Marine TACC (ashore).See JP 3-02.1, Joint Doctrine for LandingForce Operations, and NWP 3-02.2(series), Ship-to-Shore Movement, forfurther detailed discussion of theorganization and control of the VTOLassault.• Tactical-Logistical Group. TheTACLOG is a temporary agency,composed of landing force personnel,that advises the Navy controlorganization of landing forcerequirements during ship-to-shoremovement. TACLOGs assist the Navycontrol organization in expediting thelanding of personnel, equipment, andsupplies in accordance with the landingforce landing plan. TACLOGs also serveas the primary source of information tothe CLF regarding the status of landingforce units during ship-to-shoremovement. The TACLOG provides thelink between the LFSP and advises thelanding force operations center and theNavy control organizations on the statusof the offload.4. Final Preparations for theShip-to-Shore MovementUpon completion of any pre-executionoperations as described in Chapter XIII,“Supporting, Advance Force, and PreassaultOperations,” the ATF starts the final approachto assigned positions for the landings. Shipsprepare for the debarkation of the embarkedtroops, equipment, and supplies in accordancewith previously prepared plans. Thecommencement of debarkation and the timingof the ship-to-shore movement depend on thedesignated H-hour. All elements must beprepared to modify plans on short notice toconform to changes in H-hour.5. Subsidiary LandingsIn an amphibious operation, a subsidiarylanding is a landing, normally conductedby elements of the amphibious force,usually made outside the designatedlanding area to support the main landing.An amphibious operation may require one ormore subsidiary landings conducted before,during, or after the main landing. If madebefore, the effect on the main landing mustbe considered in terms of possible loss ofsurprise. Subsidiary landings must be plannedand executed by commanders with the sameprecision as the main landing. Division offorces to conduct subsidiary landings isXV-3
