The retirement of the machine guns must be effected in the usual way, each section acting independently and retiring by alternate guns—no gun moving till the other is ready in a fresh position to open fire.

When the country is flat or the features devoid of natural cover, it will be necessary to provide pits for the machine guns practically in the firing line. If this is carried out with skill, the guns may be perfectly concealed, and protected even from artillery fire. These pits should be made along the whole front and as widely scattered as possible, and when a gun is discovered by the artillery it should immediately be lowered into the pit, out of sight, where it will be perfectly safe, until the artillery directs its fire elsewhere.
