number is placed, often in chalk or some similar manner, where it can
clearly be seen on the sides and, if possible, on the front of all vehicles
in the convoy.
Each element of the number provides certain information.
These numbers, and their meaning, have been standardized in NATO through
STANAG 1059 and STANAG 2154. An example of such a number might be:
The first two figures, in this case 25, show the day of the month on
which the movement is to begin. Next are three or more figures that show
the authority that organized the move. The first two letters are the symbol
for the country involved; in this case, the United States. (See Figure 1-5.)
These letters are followed by an identification code of the command
that organized the move. In this case, it is the US Fifth Corps. The last
two numbers show the number of the movement; in this case, the 8th.
There are several reasons for using such a numbering system. It allows
the column to move along selected routes without having to stop at every
regulating point and TCP to identify itself and provide authority for its
Additionally, it allows the regulating point or TCP to more easily
report the convoy's passage to the HTD.
With the number given in the
example, should an MP patrol see a column moving on the 24th rather than the
25th, they would immediately know something was wrong and could take steps
to correct the problem.
A movement credit is the authority for a column to move over designated
routes. It shows the times when the first and last vehicles of the column
are scheduled to pass the entry and exit points on the route.
credits are obtained by units through the HTD.
How this is accomplished
will be covered under the heading REQUEST FOR CONVOY CLEARANCE.
