yed, as best suits
the occasion, or one may he used in conjunction with another.

32. Signals should be freely used in instruction, in order that
officers and men may readily know them. In making firm signals
the saber, rifle, or headdress may be held in the hand.

33. Officers and men fix their attention at the first word of
command, the first note of the bugle or whistle, or the first
motion of the signal. A signal includes both the preparatory
command and the command of execution: the movement commences as
soon as the signal is understood, unless otherwise prescribed.

34. Except in movements executed AT ATTENTION, commanders or
leaders of subdivisions repeat orders, commands, or signals whenever
such repetition is deemed necessary to insure prompt and correct
execution.

Officers, battalion noncommissioned staff officers, platoon leaders,
guides, and musicians are equipped with whistles.

The major and his staff will use a whistle of distinctive tone;
the captain and company musicians a second and distinctive whistle;
the platoon leaders and guides a third distinctive whistle.

35. Prescribed signals are limited to such as are essential as
a substitute for the voice under conditions which render the
voice inadequate.

Before or during an engagement special signals may be agreed
upon to facilitate the solution of such special difficulties
as the particular situation is likely to develop, but it must
be remembered that simplicity and certainty are indispensable
qualities of a signal.

ORDERS.

36. In these regulations an ORDER embraces instructions or directions
given orally or in writing in terms suited to the particular
occasion and not prescribed herein.

ORDERS are employed only when the COMMANDS prescribed herein do
not sufficiently indicate the will of the commander.

ORDERS are more fully described in paragraphs 378 to 383, inclusive.

COMMANDS.

37. In these regulations a command is the will of the commander
expressed in the phraseology prescribed herein.

38. There are two kinds of commands:

The PREPARATORY command, such as _forward_, indicates the
movement that is to be executed.

The command of EXECUTION, such as MARCH, HALT, or ARMS, causes
the execution.

Preparatory commands are distinguished by _italics_, those
of execution by CAPITALS.

Where it is not mentioned in the text who gives the commands
prescribed, they are to be given by the commander of the unit
concerned.
