4173 TACTICAL COMMUNICATIONS
a. Specific tactical circuits as well as special communication procedures for submarine
coordination should be identified in the OPTASK COMMS. This information should also be included in
the initial submarine assignment request. The objective is to ensure tactical communication paths and
coordinating instructions are clear to all participants and that necessary and timely intelligence
information can be rapidly exchanged between the task group and submarine.
b. GUERRILLA Procedures. The code word, GUERRILLA, is used by a submarine to indicate
that it has HIGH PRECEDENCE traffic for the SOCA or a designated commander/unit in the task group.
This code word identifies the transmitting ship as a submarine and is intended to alert other circuit
operators to clear the net as soon as possible.

c. Tactical Circuits. Communications planning should provide for primary and secondary voice
and data circuits for use with the SOCA as well as alternate circuits for urgent communication with any
element of the task group. The intent is to provide the submarine a best bet circuit when time is of the
essence, while limiting the need for frequent changes in the submarines basic communications plan setup.
First priority should be satellite communications (if fitted), followed by line-of-sight UHF, and HF.
Changes that do occur should be reflected in periodic Force Summary message updates.
