Figure 2-4.
Critical Time and Point Graph.
When the road net is adequate for the volume of military traffic, a
critical time and point graph and the schedule it represents may be
fairly firm weeks in advance. However, tactical or other situations
may require that a high-priority convoy use the roads on sudden
notice.
If so, you may have to notify the commander of a lower
priority convoy of a new routing or schedule on short notice.
You
can forward changes of the graph to the convoy commander through
highway movement control teams (HMCTs).
However, you must change
your
critical
time
and
point
graph
before
issuing
change
instructions.
This is to ensure against further conflicts that may
be caused by new routings or schedules.
