Priority, Immediate, and Flash. Figure 2-13 shows
examples of the different types of precedence.
complete information concerning message pre-
cedence is contained in Naval Telecommunica-
tions Procedures (NTP), Telecommunications
Users Manual, NTP 3(H).
Routine. Routine is the precedence assigned to
all types of traffic that justify electrical
transmission but are not of sufficient urgency to
require a higher precedence. The Routine pre-
cedence is identified by the prosign R.
Priority. Priority is the precedence reserved
for messages that furnish essential information
for the conduct of operations in progress. That
is the highest precedence normally authorized for
administrative messages. Priority precedence is
identified by the prosign P.
Immediate. Immediate precedence is
reserved for messages relating to situations that
gravely affect the national forces or populace and
require immediate delivery to addressees. Im-
mediate precedence is identified by the prosign O.
Flash. Flash precedence is reserved for initial
enemy contact reports or operational combat
messages of extreme urgency. Message brevity is
mandatory in Flash messages. Flash precedence
is identified by the prosign Z.
Another precedence is the Emergency Com-
mand. The Emergency Command precedence
(ECP) is not commonly used but preempts all
other precedence. Its use is limited to the National
Command Authority, certain designated com-
manders of unified and specified commands, and
specifically designated emergency action com-
mand and control messages. When used, ECP is
identified by the prosign Y.
Messages having both action and information
addressees may be assigned a single precedence
or a dual precedence. A dual precedence exists
when a higher precedence is assigned to action
addressees than to information addressees. The
assignment of a dual precedence must be con-
sidered on all messages with information ad-
dressees when other than routine precedence is
assigned to the action addressee(s).
REACTION TIME. -The precedence
assigned to a message has no direct effect on the
time by which a reply must be sent or on the
precedence assigned to that reply. Each activity
must establish its own requirements concerning
the acknowledgment of messages. The following
factors should be considered when submitting a
reply to a message:
1. Does the message have a reply due date?
2. Must the reply be forwarded by
telecommunication message, or can it be
sent by naval letter or NAVGRAM?
Regardless of the reaction times established
locally, Flash and Emergency Command pre-
cedence messages requiring a reply must always
be handled as quickly as possible. In some cases,
you may be required to forward a reply to the
originator in less than 30 minutes.
The date-time group (DTG) is assigned to
messages for identification purposes only. The
DTG consists of six digits followed by a time-zone
suffix (for example, 021930Z). The first pair of
digits (02) denotes the day of the month; the
second pair (19) indicates the hour; and the third
pair (30), the minutes. All DTGs are expressed
in Greenwich Mean Time (Z) unless otherwise
directed by higher authority. In addition, the
abbreviated month and year of origin are ap-
pended to the DTG. Therefore, the DTG 021930Z
JAN 91 would be identified as a message being
officially released from a communications facility
for transmission at 1930 hours, Greenwich Mean
Time, on the 2nd of January 1991.
Although not considered as part of the date-
time group, the originators name must be
included in the identification of a specific
message. For example, NETPMSA Pensacola FL
032115Z MAY 91 indicates a specific message
originated by Naval Education and Training
Program Management Support Activity, Pensa-
cola, Florida. However, a message identified only
by the DTG 032115Z MAY 91 is not properly
identified since any command in the Navy could
have released a message with the same DTG.
Figure 2-14 shows the Joint Message Form
(DD-173/2). Naval Telecommunications Pro-
cedures (NTP), Telecommunications Users
Manual, NTP 3(H), and U.S. Navy Plain
Language Directory, NTP 3, SUPP-1 (K), give the
fundamental format and procedures for preparing
the naval message.
ADDRESS COMPONENTS. The address
consists of the plain language address (PLA); the
message originator; and the action, information,
