Precedence

Lesson 5/Learning Event 2

The heading of the message will consist of the following information in this order.

Precedence. The dissemination precedence assigned to NBC 5 (Chemical/Biological) Reports will

be IMMEDIATE.

Date/time. This date and time is the date and time the message is sent. It may be given in local or

ZULU time, but it must be indicated which time is used (e.g. 280730Z or 280730 local).

Security Classification. Normally the message will be UNCLASSIFIED.

From . This line will contain the designation of the agency sending the message.

To. This line will designate the unit or units that are to receive the message.

Type of Report. This line will contain NBC 5 (Chemical) or NBC 5 (Biological).

The information to be entered in the body of the message is as follows:

Line ALFA. This line will contain the strike serial number assigned by the NBCE upon receipt of

the initial NBC 1 (Chemical/Biological) Report for that attack.

Line SIERRA. On this line the date and time the contamination was initially detected will be

entered. This time may be in either local or ZULU time, but the time used must be shown.

Line TANGO. On this line the date and time of the latest survey of contamination will be shown.

Line XRAY. This line will show a series of coordinates taken from the situation map along the

contour outlining the contaminated area. There is no specific number of coordinates to be used;

however, there should be a sufficient number to insure that, when the NBC 5 (Chemical/Biological)

Report is posted by the subordinate unit, the contour can be drawn as accurately as possible. When

the series of coordinates form a closed ring, the last coordinate should be the same as the first.

Shown in figure 36 on page 88 is an area of chemical contamination. The coordinates, which are

marked by x's in the contour shown on page 88, are the coordinates shown in line XRAY of the

NBC 5 (Chemical) Report (figure 37 on page 89).
