their final movement to the beach. When landing
beaches are separated, each beach has its own LOD,
which may be marked by a ship or ships of the control
organization or by boats or buoys. In some landings
the LOD may not be marked.
Boat lanes extend seaward from the landing beach
to the LOD. The length of the landing beach
determines the width of the boat lane. The flanks of
the boat lane may be marked at the LOD by a control
ship, a marker boat, or a buoy.
Approach lanes are extensions of the boat lanes
from the LOD towards the transport area. They may
be terminated by marker ships, boats, or buoys.
Adjacent approach lanes may be parallel or may
diverge seaward to provide for early dispersion of the
assault waves. Approach lanes indicate the exact
routes for craft to use in approaching the LOD.
There is a maximum of ten debarkation stations,
five on the starboard side and five on the port side,
each identified by color and number (odd-numbered,
starboard; even-numbered, port). See figure 12-4.
