Individual Activity Address Groups
Individual activity address groups are
representative of a single command or unit, either afloat
or ashore. For example:
DTCI—COMNAVSURFLANT; and
SSMA—CHIEF OF NAVAL OPERATIONS (CNO).
Collective Address Groups
Collective address groups represent two or more
commands or activities. Included in this group are
commanders and their subordinate commanders. For
example:
JTBC—DESRON 6; and
YQHV—SUBRON 16.
Conjunctive and Geographic Address Groups
Conjunctive and geographic address groups are
discussed together because they are interrelated in their
usage.
Conjunctive address groups have incomplete
meanings and must have geographic address groups
added to them to denote a specific command or location.
For this reason, conjunctive address groups are used
only with one or more geographic address groups. For
example, the conjunctive address group XZKW means
“All ships present at ___ .” To complete the meaning,
it must be followed by a geographic address group.
Geographic address groups are the equivalent of
geographical locations or areas. They are always
preceded by conjunctive address groups. For example,
the address group DEXL could represent Newport, R.I.
Therefore, all ships present at Newport would be
addressed XZKW DEXL.
Address Indicating Groups
Address indicating groups (AIGs) represent 16 or
more specific and frequently recurring combinations of
action and/or information addressees. The purpose of
AIGs is to increase the speed-of-traffic handling. They
shorten the message address by providing a single
address group to represent a large number of addressees.
This eliminates individual designators for each address
used in the heading.
Messages that are repetitively addressed to a
constant group of 16 or more addressees can effectively
be processed by an AIG address designator. For
example, let’s assume that a hypothetical AIG (AIG 31)
is used to address SUBMISS/SUBSUNK message
traffic by COMSUBLANT to 30 action addressees and
35 information addressees. Since a single AIG (AIG
31) is used, 65 call signs and address groups are
eliminated from the heading of the message.
AIGs are normally created when particular types of
message traffic become repetitive enough (at least 12
times a year) and are addressed to enough of the same
addressees to warrant it. Among such message traffic
are:
l
l
l
l
l
l
Alerts, air defense warnings, operational or
emergency actions, and so forth;
Destructive weather warnings, such as
hurricanes and typhoons;
Logistical transactions and reports;
Intelligence summaries;
Movement reports, such as aircraft, ships, and
personnel; and
Notices to airmen (NOTAMs).
A point for you to remember is that an AIG will not
be established for groups of addressees numbering
fewer than 16. A complete listing of AIGs by number,
cognizant authority, and purpose is contained in U.S.
Navy Address Indicating Group (AIG) and Collective
Address Designator (CAD) Handbook, NTP 3 SUPP-1.
A partial listing of AIGs, along with specific action and
information addressees, can be found in ACP 100 U.S.
SUPP 1.
Special Operating Groups
Special operating groups (SOGs) are four-letter
groups that are identical in appearance to address
groups. SOGs are provided for use in the headings of
messages to give special instructions. However, SOGs
are not used unless specifically authorized by CNO.
They must always be encrypted. SOGs may be used
singly or with encrypted or unencrypted call signs or
address groups.
DISTRIBUTION CLERK
The distribution clerk reproduces copies of the
messages according to the routing instruction of the
inrouter and outrouter. The distribution clerk is
responsible for making the required number of copies
