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.

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 be 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, mar
