war, suffer death or such other punishment as a
court-martial may direct. (See par. 171.)

210. The COUNTERSIGN is a word given daily from the principal
headquarters of a command to aid guards and sentinels in identifying
persons who may be authorized to pass at night.

It is given to such persons as may be authorized to pass and
repass sentinels' posts during the night, and to officers,
noncommissioned officers, and sentinels of the guard.

211. The PAROLE is a word used as a check on the countersign
in order to obtain more accurate identification of persons. It
is imparted only to those who are entitled to inspect guards
and to commanders of guards.

The parole or countersign, or both, are sent sealed in the form
of an order to those entitled to them.

212. When the commander of the guard demands the parole, he will
advance and receive it as the corporal receives the countersign.
(See par. 133.)

213. As the communications containing the parole and countersign
must at times be distributed by many orderlies, the parole intrusted
to many officers, and the countersign and parole to many officers
and sentinels, and as both the countersign and parole must, for
large commands, be prepared several days in advance, there is
always danger of their being lost or becoming known to persons
who would make improper use of them; moreover, a sentinel is
too apt to take it for granted that any person who gives the
right countersign is what he represents himself to be; hence for
outpost duty there is greater security in omitting the use of
the countersign and parole, or in using them with great caution.
The chief reliance should be upon personal recognition or
identification of all persons claiming authority to pass.

Persons whose sole means of identification is the countersign, or
concerning whose authority to pass there is a reasonable doubt,
should not be allowed to pass without the authority of the corporal
of the guard after proper investigation; the corporal will take
to his next superior any person about whom he is not competent
to decide.

214. The COUNTERSIGN is usually the name of a battle; the PAROLE,
that of a general or other distinguished person.

215. When they can not be communicated daily, a series of words
for some days in advance may be sent to posts or detachments that
are to use the same parole or countersign as the main body.

216. If the countersign be lost, or if a member of the guard
