UNITED STATES AR^tY, 1914. 



[The numbers refer to paragraphs in the Manual.] 

 Section 1. Introduction. 



1. Guards may be divided into four classes : Exterior guards, 

 interior guards, military police, and provost guards. 



2. Exterior guards are used only in time of war. They be- 

 long to the domain of tactics and are treated of in the Field 

 Service Regulations and in the drill regulations of the different 

 arms of the service. 



The purpose of exterior guards is to prevent surprise, to 

 delay attack, and otherwise to provide for the security of the 

 main body. 



On the march they take the form of advance guards, rear 

 guards, and flank guards. At a halt they consist of outposts. 



3. Interior guards are used in camp or garrison to preserve 

 order, protect property, and to enforce police regulations. In 

 time of war such sentinels of an interior guard as may be 

 necessary are placed close in or about a camp, and normally 

 there is an exterior guard further out consisting of outposts. 

 In time of peace the interior guard is the only guard in a camp 

 <>i" garrison. 



4. Military police differ somewhat from either of these 

 classes. (See Field Service Regulations.) They are used in 

 time of war to guard prisoners, to arrest stragglers and de- 

 serters, and to maintain order and enforce police regulations 

 in the rear of armies, along lines of communication, and in 

 the vicinity of large camps.
