280 MANUAL FOE NONCOMMISSIONED OFFICERS. 



194. If a party is already advanced and in communication 

 witli a sentinel, the latter will challenge any other party that 

 may approach ; if the party challenged be senior to the one 

 already on his post, the sentinel will advance the new party 

 at once. The senior may allow him to advance any or all of 

 the other parties ; otherwise the sentinel will not advance any 

 of them until the senior leaves him. He will then advance 

 the senior only'of the remaining parties, and so on. 



185. The foih)wing order of rank will govern a sentinel in 

 advancing different persons or parties approaching his post: 

 Commanding officers, officer of the day, officer of the guard, 

 officers, patrols, reliefs, noncommissioned officers of the guard 

 in order of rank, friends. 



196. A sentinel will never allow himself to be surprised, nor 

 permit two parties to advance upon him at the same time. 



197. If no countersign be used, the rules for challenging are 

 the same. The rules for advancing parties are modified only 

 as follows : Instead of saying "Advance (so-and-so) with the 

 countersign," the sentinel will say "Advance (so-and-so) to 

 be recognized." Upon recognition he will say, "Advance (so- 

 and-so.)" 



198. Answers to a sentinel's challenge intended to confuse or 

 mislead him are prohibited, but the use of such an answer as 

 " Friends with the countersign," is not to be understood as 

 misleading, but as the usual answer made by officers, patrols, 

 etc., when the purpose of their visit makes it desirable that 

 their official capacity should not be announced. 



SPECIAL ORDERS FOR SENTINELS AT THE POST OF THE GUARD. 



199. Sentinels posted at the guard will be required to mem- 

 orize the following: 



Between reveille and retreat to turn out the guard for all 

 persons designated by the commanding officer, for all colors or 

 standards net cased, and in time of war for all armed parties 

 approaching my post, except troops at drill and reliefs and 

 detachments of the guard. 



At night, after challenging any person or party, to advance 

 no one but call the corporal of the guard, repeating the answer 

 to the challenge.
