During a ship-to-shore surface assault on a hostile beach, a certain number of casualties among the assault craft are inevitable. The mission of the salvage organization is to keep boat lanes and beachheads clear of disabled assault craft so that movement to the beach is maintained. CRAFT INVOLVED IN SALVAGE Wave commanders control their boats by means OPERATIONS of hand signals, as shown in figure 12-16. A heavy salvage boat is normally an LCM converted as stated in BOATALT 19C, dated 05/10/63, and is stationed outside the surf zone but close enough A light salvage boat is normally an LCPL and is stationed seaward of the surf zone along the boat lanes as required. Salvage teams should consist of personnel from one ship trained as a team to maintain consistency. Personnel for salvage teams should be assigned as shown in figure 12-15. NOTE One team member must be a qualified search and rescue (SAR) swimmer. The boat equipage for the heavy salvage and the ABGC/light salvage boats is detailed in NWP 22-3. DISPATCHING VESSELS The visual signals used to dispatch the boat waves from the LOD are displayed by both the primary and secondary control vessels. Every wave commander has a radio in the boat, and the foregoing signals are paralleled by radio signals. At night, lighted wands or flashlights are used. The positions are the same as for the day signals. Lights are turned on when the hands are in the starting positions and turned off when the signals have been HEAVY SALVAGE BOAT LIGHT SALVAGE BOAT 1 - Salvage officer 1 - BM2/BM3 (salvage rigger) 1 - BMC/BMl (salvage rigger) 1 - SM3/SMSN 1 - ENl/EN2 1 - HT2/HT3 1 - HT2/HT3 1 - RM3/RMSN 1 - RM3/RMSN l - SN 1 - SM3/SMSN 1 - HM3/HMSN l - SN Figure 12-15.—Salvage team personnel. 12-23
