The shift to channel ALFA can be ordered by
PCS when desired, but no later than when boat
waves cross the LOD. If no channel shift order
is given, boat waves will automatically shift to
channel ALFA upon crossing the LOD.
Amphibious assault vehicle (AAV) waves
require an intention statement from PCS when
PCS takes positive control.
A full call-up is required for all transmissions to
ensure that the proper wave received the
information. When ordering courses to boat
waves, make sure they are given in magnetic
All reports to the CCO should include a time

Because many boat compasses are unreliable, it
is best to change the course of boats by vectors
of 10 degrees to 30 degrees instead of course
headings. To minimize the initial error and
consequent loss of time, the BGC, ABGC, and
all BWCs should check and compare their
magnetic compass headings with the PCS while
transmitting from the wave-forming circles to
the landing craft rendezvous area. Vectors may
be given at any time to maintain a wave's
position in the boat lane center. However,
vectors should be held to 10 degrees or less in
the surf zone for boat safety.
Waves outside the boat lanes must be vectored
to regain boat lane positioning.
Prior to the order for BS, speed changes may be
given at any time to keep waves on time. Speed
changes must be ordered when waves are early
or late 2 minutes or more.
BS must be ordered at the 1,000-yard mark.
Even if a wave is doing maximum speed before
the 1,000-yard mark, the order BATTLE
SPEED is still mandatory at that time.
Note that all information transmissions end in
OUT and those directing waves to perform a
duty end in OVER. If at any time you desire a
wave to acknowledge receipt of information,
end the transmission with OVER, thus requiring
Dispatched orders are not required if waves have
been shifted to channel ALFA or the shift to
channel ALFA upon each waves crossing LOD
is provided for in the OPORDER or prebrief.
VISUAL PROCEDURES FOR
TRANSMITTING GRID POSITIONS
LEARNING OBJECTIVE: Explain procedures
for visually transmitting grid positions.
Grid positions by flashing light or Nancy will
normally be preceded only by flashing the wave
number. However, if confusion would result from
transmitting into different numbered boat lanes or
different colored beach lanes, it will be necessary to
modify the call accordingly. For example, to call the
wave commander of Wave Three, Blue Beach Two,
the normal call-up is the numeral 3. If confusion would
result, and it is therefore necessary to send the
complete call, the call is transmitted as numeral 3,
Blue, numeral 2. The control ship, after establishing
communications with the wave commander, then
transmits the grid position.
The wave commander receipts for each group by
flashing a T with his or her signal equipment and
receipts for the message with the usual R.
Visual grid positions and information are
transmitted by control ships using the procedures in
the following paragraphs.
After the wave call-up, insert the group GP. This
acts as a proword and alerts the receiver that a grid
position is to follow.
