Transmit the grid position using letter L for left, C for center, R for right, and LL or RR for being outside of the boat lane to the left or right, respectively. The distance from the beach is transmitted in hundreds of yards as a single or double numeral. For instance, 1 equals 100 yards; 11 equals 1,100 yards. Transmit the letter T followed by two digits to indicate the time, in minutes, of the grid position. Given the time of the position, the wave commander knows how early or late he or she is once the position is plotted. Knowledge of grid position time is important because, depending on the proficiency of the control team, receipt of the position can be up to 2 minutes after actual time. If necessary to order a speedup or slowdown, the group SS or TT is sent, respectively. If necessary to order a course change, a vector in tens of degrees indicating direction left or right is sent. For instance, to vector 30 degrees to the right, the group V3R is sent. Direction of the vector should always be included, because waves are not necessarily always heading for the beach but may be under control seaward towards the rendezvous area. The group BS BS is an order to go to BATTLE SPEED. If needed, the group TA indicates an order to turn away. The following are examples of grid posits sent visually: SIGNAL 4GPL4OT32 MEANING Wave four grid posit is in the left portion of the boat lane 4,000 yards from the beach at time 32. 2GPR32T47SS Wave two grid posit is in the right portion of the boat lane 3,200 yards from the beach at time 47 and is to speed up. lGPLL29T52V2R Wave one grid posit is outside of the boat lane to the left 2,900 yards from the beach at time 52 and is ordered to vector 20 degrees to the right. 3GPC20T17TT Wave three grid posit is in the center of the boat lane 2,000 yards from the beach at time 17 and is ordered to slow down. Upon touchdown of the first boat/vehicle of each wave, the signal TD TD TD is sent to the control ship. Remember, its going to be very difficult at times to transmit back or receive from the control ship; you must be proficient and get the job done. Visual communication is a very important part of an amphibious assault, so be prepared to do your best. QUIET LANDING PROCEDURE LEARNING OBJECTIVE: Explain the method of control for quiet landing, including visual signals, radio circuit, and manning requirements. Visual signaling (flashing light, flaghoist, and/or semaphore) will be used as the primary means of controlling the movement of surface craft during the initial assault portion of a quiet landing. Radio circuits normally used in controlling the ship-to-shore movement should be checked out before the assault, subject to emission control (EMCON) policy. These radio circuits should be guarded and should be used only when all other means of communicating with surface assault waves have failed and when it is necessary to correct or alter the movement of an assault wave. It is imperative that experienced Signalmen be embarked in control boating. They must watch the control ship constantly and must be capable of receiving at the rate of eight words per minute. Since embarked craft (LCUs and LCMs) do not normally include Signalmen in deploying boat crews, host ships should ensure that a Signalman is assigned to embarked craft for assault operations. PCS will transmit a vector and speed signal to each wave at l-minute intervals once the wave has been dispatched from the LOD. The signal will be in three parts: wave identification, vector, and speed. Identification of the wave is signaled by the corresponding numeral. Vector direction is indicated by flashing ROMEO for right and LIMA for left. The amount of vector is indicated by the multiple letters, each representing 10°; for example, R indicates vector right 10°, and RRR indicates to vector right 30°. If vectoring is not necessary, the letter CHARLIE is signaled. Speed orders will be signaled by numerals indicating 12-22
