Be especially watchful at night and during the time for challenging, to challenge all persons on or near my post, and to allow no one to pass without proper authority.
(1) If a sentry observes a person approaching post during the time for challenging, the sentry calls; “HALT, who is there?”, while the person is still far enough away for the sentry to take effective measures should the person rush after being challenged. Before challenging, the sentry takes the most advantageous covered and/or concealed position from which to identify, detain, or apprehend the person or party. In effecting identification, the sentry may require the challenged person or one of a party to move as necessary to affect positive and prompt recognition. Normally upon receiving an answer to the challenge, the sentry will command; “Advance, (repeats the answer to the challenge such as “Officer of the Day”) to be recognized.” The sentry halts the person advanced again, at a point where recognition can be affected.
- (a) Positive recognition of all persons claiming authority to pass is the sentry’s main consideration. The sentry must ascertain that those challenged are, in fact, the persons they represent themselves to be and have authority to be there before permitting them to pass. If not satisfied as to their identity, the sentry will detain the person or party and call the COG.
- (b) The sentry will permit only one member of a party to approach the post for the purpose of recognition. On receiving an answer that indicates the party is friendly and may be authorized to pass, the sentry will command. “Advance one to be recognized.” When that one has been recognized, the sentry directs the person to bring up the rest of the party and to identify each individual as he/she passes.
(2) If two or more persons or parties approach the sentry’s post from different directions at the same time, they will be challenged in turn and required to halt and remain halted until advanced. A sentry never permits more than one person to advance at the same time. The senior person or party is the first advanced.
(3) If a person or party is already advanced and in conversation with a sentry, the latter will challenge any other person or party that may approach. If the new person or party challenged is senior to the one already on the post, the sentry will advance the new person; otherwise, the sentry will advance no one until the first person or party leaves.
(4) Answers to a sentry’s challenge intended to confuse or mislead are prohibited, but the use of such an answer as “friend” is not to be construed as misleading. It is the usual answer made by officers or patrols when the purpose of their visit makes it desirable that their official capacity should not be announced.
