The length of the road, or portion to which the
formula is being applied may be listed next. It may be omitted. When it is
shown, it is placed in parentheses, e.g., (7.2 km).
This entry in the formula is identical with
the obstruction entry in the route classification formula.
(g) Special Conditions. Snow blockage and flooding are entered
in the formula at this point, just as they are in the route classification
The symbols are the same, i.e., T for snow and W for possible
Road Classification Examples:
A 5.4/6.2m k:
This road has no limiting characteristics.
The traveled way is 5.4 meters. The total width of the road is 6.2 meters.
It has a concrete surface.
Bcgs 14/16 ft 1 (2.4km)(OB):
The road has limiting
characteristics of sharp curves, steep grades, and a rough surface. It has
a traveled way of 14 feet and a combined width of 26 feet. The surface is
gravel or lightly metaled.
The length of the road described is 2.4
kilometers and it has obstruction.
Record Tactical Intelligence Data.
While you are gathering the information to determine the route
and road classification, you must also gather other categories of
A major category of information that must be obtained is
information of a tactical intelligence nature. Certain items of information
are of critical importance to the commander.
What they are will vary
constantly. When you were given the mission order for the patrol, you were
told what these items were.
They were termed the essential elements of
requirements (PIR). The second category is termed information requirements
(IR). PIR are the items that must be given priority. It does not mean they
are the only elements of information that should be collected.
