ar manner the director may inform Sergeant B (or any
member of the patrol) that this hostile patrol is followed by
a squad (on the assumption that it is the leading unit of an
advance guard), and the exercise is then continued along these
lines.

The following are examples of assumption that might be made and
carried out:

(a) That the patrol is unexpectedly fired upon.

(b) That one or more of the patrol is wounded.

(c) That a prisoner is captured (let an observer act as
prisoner).

(d) That a friendly inhabitant gives certain information.

(e) That a dust cloud is seen in the distance over the trees.

(f) That a column of troops can be seen marching along
a distant road.

(g) That an abandoned camp is discovered and certain signs
noted.

(h) That the patrol is attacked by a superior force and
compelled to scatter.

There is practically no end to the number of reasonable assumptions
that may be made.

Company officers may use this method of instructing non-commissioned
officers in patrolling, advance and rear guard duty, outposts,
and in squad leading, in writing messages, in selecting positions
for trenches, and in constructing and concealing same. This form
of instruction is called "a tactical walk." It is very greatly
used by all foreign armies. Exercises along the same general
lines are conducted for field and staff officers and even general
officers, and are called "tactical rides" and "strategical rides,"
depending upon their object.

After some proficiency has been attained as a result of these
tactical walks, the greatest interest and enthusiasm can be awakened
in this work by sending out two patrols the same day, one to
operate against the other. Each should wear a distinctive uniform.
The strength of each patrol, its starting point, route to be
followed, and its orders should all be unknown to the other patrol.
If blank ammunition is used, an officer should supervise its
issue and carefully inspect to see that no man carries any ball
cartridges. One umpire should accompany the commander of each
party. Each umpire should be fully informed of the strength,
orders, and route of both patrols. He must, however, carefully
avoid giving suggestions or offering any information to the
commander. Observers in these small maneuver problems are generally
in the way and none should be permitted to be along.

These small maneuvers may be gradually developed by having one
side establish al outpost or fi
