[604.] The following paragraphs on patrols are placed here for convenience. They relate in particular to the conduct of the patrol and its leader, and apply to patrols employed in covering detachments as well as in combat reconnaissance.
[605.] A patrol is a detachment sent out from a command to gain information of the country or of the enemy, or to prevent the enemy from gaining information. In special cases patrols may be given missions other than these.
[606.] The commander must have clearly in mind the purpose for which the patrol is to be used in order that he may determine its proper strength, select its leader, and give the latter proper instructions.
In general, a patrol should be sent out for one definite purpose only.
[607.] The strength of a patrol varies from two or three men to a company. It should be strong enough to accomplish its purpose, and no stronger.
If the purpose is to gain information only, a small patrol is better than a large one. The former conceals itself more readily and moves less conspicuously. For observing from some point in plain view of the command or for visiting or reconnoitering between outguards two men are sufficient.
If messages are to be sent back, the patrol must be strong enough to furnish the probable number of messengers without reducing the patrol to less than two men. If hostile patrols are likely to be met and must be driven off, the patrol must be strong.
In friendly territory, a weaker patrol may be used than would be used for the corresponding purpose in hostile territory.
[608.] The character of the leader selected for the patrol depends upon the importance of the work in hand.
For patrolling between the groups or along the lines of an outpost, or for the simpler patrols sent out from a covering detachment, the average soldier will be a competent leader.
