Types of Patrols in Trench Warfare
RECONNAISSANCE PATROLS
Are the work of scouts who go out on some specific mission. Numbers should be as small as possible. A party of two or three will probably obtain the best results.
FIGHTING PATROLS
Should consist of Lewis gun and gunners, bombers and scouts. Strength 10–15. Object to disperse enemy working parties, to engage enemy patrols, to obtain identifications.
Note:—It may often be necessary to combine these patrols; the Fighting Patrol going out to form a screen in rear, while the Reconnaissance Patrol pushes forward to complete its task. This has the effect of giving the Reconnaissance Patrol confidence, of assisting them to pass back any casualties they may suffer, and, in fact, provides them with an Advanced Headquarters from which they carry out their reconnaissance. The system is particularly useful, and, in fact, necessary, where a great distance separates the opposing lines.
PROTECTIVE PATROLS
Should consist mainly of Bombers, and are used in front of our wire, or between Isolated Posts. Numbers depend on circumstances. Object: Protection of our line from surprise attacks.
Open Warfare
It is not necessary here to classify definitely. The Reconnoitring Patrol should always be prepared to fight. In fact, all Patrols, at all times, should be fully organized self-contained fighting units. Numbers depend on conditions, but Scouts will be largely used.
