[620.] Infantry patrols are generally used for work within 2 miles of supporting troops, but cases arise where they must go to greater distances.
[621.] Patrols composed of mounted scouts are conducted like cavalry patrols and should be trained in accordance with the Cavalry Drill Regulations.
For distant patrolling, a mounted patrol under an officer should be used.
[622.] For controlling the movements of the patrol, the leader should, when necessary, make use of the arm signals prescribed in these regulations.
On account of the short distances separating them, ordinary communication between members of the patrol is best effected quietly by word of mouth.
When a member of a patrol is sent to a distant point, communication may be effected by means of simple, prearranged signals.
When practicable, the patrol leader may communicate with the main body by means of visual signaling.
