arts A-B, B-C, C-D and D-E. Platoon No. 1 would
look after everything that appeared in D-E; No. 2, after everything
that appeared in C-D; No. 3, everything that appeared in B-C; and No.
4, after everything that appeared in A-B.

Should the target suddenly disappear from D-E, then No. 1 would switch
his fire over to C-D, and keep it there until the target reappeared in
D-E, and if the targets disappeared from C-D, before reappearing in
D-E, then both No. 1, and No. 2, would switch their fire cones to A-C.

=1450. Exercises.= The following exercises for the elementary training
of individuals and squads were used with success by the troops
mobilized on the Texas border:

TARGETS

1. The target will be represented by individual soldiers.

2. With reference to their visibility, the battlefield will present
three classes of targets:

(a) Those which are visible throughout.

(b) Those which are visible in part.

(c) Those which are invisible, but whose location might be
described.

Targets will be arranged to simulate one of the classes enumerated.
Instruction will begin with simple exercises in which the target
presented is plainly visible, and represents only the objective of the
unit undergoing instruction. It should progress to the more difficult
exercises in which the target is invisible and the line of figures is
prolonged to include the objective of units on the right or left.

3. The limits of indistinct targets may be shown to unit commanders by
the use of company flags. These flags, however, will be withdrawn from
sight before a description of the target or estimate of the range is
attempted, and before anyone but the commander of the unit undergoing
instruction sees their location.

4. At the conclusion of each exercise in which flags are used to mark
the limits of the target or its subdivisions, they should be
displayed, in order that any existing errors may be readily pointed
out.

5. To determine proficiency in target designation, the instructor will
provide a sufficient number of rifles, placed on sand bags or other
suitable rests, and require those charged with fire direction and
control to sight them at the limits of their objective. An inspection
by the instructor will at once detect errors. Similarly, in those
exercises in which all the members of the firing unit participate, the
percentage of rifles aimed at the correct target may be determined.

6. In these exercises no m
