fficers and
noncommissioned officers not required to complete the full quota of
the units participating are assigned as observers or umpires.

The firing line can rarely be controlled by the voice alone; thorough
training to insure the proper use of prescribed signals is necessary.

The exercise should be followed by a brief drill at attention in order
to restore smartness and control. (6)

=56. Imaginary, outlined and represented enemy.= In field exercises
the enemy is said to be =imaginary= when his position and force are
merely assumed; =outlined= when his position and force are indicated
by a few men; =represented= when a body of troops acts as such. (7)

General Rules for Drills and Formations

=57. Arrangement of elements of preparatory command.= When the
=preparatory= command consists of more than one part, its elements are
arranged as follows:

(1) For movements to be executed successively by the subdivisions or
elements of an organization: (a) Description of the movement; (b) how
executed, or on what element executed.

(For example: =1. Column of Companies, first company, squads right. 2.
March.=--Author.)

(2) For movements to be executed simultaneously by the subdivisions of
an organization: (a) The designation of the subdivisions; (b) The
movement to be executed. (For example: =1. Squads right. 2.
March.=--Author.) (8)

=58. Movements executed toward either flank explained toward but one
flank.= Movements that may be executed toward either flank are
explained as toward but one flank, it being necessary to substitute
the word "left" for "right," and the reverse, to have the explanation
of the corresponding movement toward the other flank. The commands are
given for the execution of the movements toward either flank. The
substitute word of the command is placed within parentheses. (9)

=59. Any movement may be executed from halt or when marching unless
otherwise prescribed.= Any movement may be executed either from the
halt or when marching, unless otherwise prescribed. If at a halt, the
command for movements involving marching need not be prefaced by
=forward=, as =1. Column right (left), 2. MARCH=. (10)

=60. Any movement may be executed in double time unless specially
excepted.= Any movement not specially excepted may be executed in
double time.

If at a halt, or if marching in quick time, the command =double time=
precedes the command of execution. (11)

=61. Successive movements execute
