The PREPARATORY command should be given at such an interval of
time before the command of EXECUTION as to admit of being properly
understood; the command of EXECUTION should be given at the instant
the movement is to commence.

The tone of command is animated, distinct, and of a loudness
proportioned to the number of men for whom it is intended.

Each PREPARATORY command is enunciated distinctly, with a rising
inflection at the end, and in such manner that the command of
EXECUTION may he more energetic.

The command of EXECUTION is firm in tone and brief.

39. Majors and commanders of units larger than a battalion repeat
such commands of their superiors as are to be executed by their
units, facing their units for that purpose. The battalion is the
largest unit that executes a movement at the command of execution
of its commander.

40. When giving commands to troops it is usually best to face
toward them.

Indifference in giving commands must be avoided, as it leads
to laxity in execution. Commands should be given with spirit at
all times.

BUGLE SIGNALS.

41. The authorized bugle signals are published in Part V of these
regulations.

The following bugle signals may be used off the battle field,
when not likely to convey information to the enemy:

ATTENTION: Troops are brought to attention.

ATTENTION TO ORDERS: Troops fix their attention.

FORWARD, MARCH: Used also to execute quick time from double time.

DOUBLE TIME, MARCH.

TO THE REAR, MARCH: In close order, execute SQUADS RIGHT ABOUT.

HALT.

ASSEMBLE, MARCH.

The following bugle signals may be used on the battlefield:

FIX BAYONETS.

CHARGE.

ASSEMBLE, MARCH.

These signals are used only when intended for the entire firing
line; hence they can be authorized only by the commander of a unit
(for example, a regiment or brigade) which occupies a distinct
section of the battle field. Exception: FIX BAYONET. (see par.
318.)

The following bugle signals are used in exceptional cases on
the battle field. Their principal uses are in field exercises
and practice firing.

COMMENCE FIRING: Officers charged with fire direction and control
open fire as soon as practicable. When given to a firing line,
the signal is equivalent to fire at will.

CEASE FIRING: All parts of the line execute CEASE FIRING at once.
These signals are not used by units smaller than a regiment, except
when such unit is independent or detached from its regiment.
