11. The wide extensions of modern armies will often make it impossible for any but mounted troops to be concentrated at decisive points—either to make the most of favourable opportunities, or to ward off an unexpected danger. Mounted machine-gun detachments will be very valuable for such purposes.
12. In the attack of a defensive position deliberately occupied, part of the machine guns will at first be held in reserve, but, according to the latest opinions formed from the lessons of the Russo-Japanese War, the majority of the machine guns will support the advance of the infantry. They are especially effective in keeping down the defenders’ fire during the last stage of the attack when the artillery is no longer able to fire over the heads of the infantry.
13. On the defensive it is advisable that a considerable number of machine guns should be held in reserve, especially with a view to preventing any unexpected turning movements, repelling assaults, delivering counter-attacks, and in case of such reinforcing any threatened points in the line of defence. In fortified positions machine guns may be usefully employed in front of the position to force the enemy to deploy prematurely. His artillery as it comes into action will frequently offer very suitable targets. The majority of machine guns, however, will be placed in the line of defence (or at least immediately in rear of the sections to which they are allotted) as soon as the direction of the enemy’s attack has been ascertained. This presence in the front line will make it possible to reduce the number of men actually in that line and will thus economise troops.
14. In the pursuit machine guns will be especially effective against the flanks and rear of the retiring enemy. Again, in covering a retirement and checking the enemy’s pursuit, machine guns with cavalry and artillery will delay the enemy’s advance and enable their own infantry to break away. In this case the first duty will be to protect their own artillery.
15. With the Independent Cavalry machine guns form a very valuable addition to the effective strength both for defence and offence. Even in reconnaissance work they will be able to break down the enemy’s resistance at certain points (villages) and to increase the tenacity of their own forces in the defence of similar points. Light machine guns carried on the saddle would be of the greatest assistance to smaller bodies of cavalry in such circumstances. Machine guns are also valuable in purely cavalry engagements, especially when it is possible for them to take the enemy in flank. If this be impossible, they can effectively follow up a success, or cover the retirement of their own cavalry. If some of the machine guns act as escort to the artillery, the cavalry escort can be dispensed with. This will increase the effective strength of the cavalry and also give the artillery a wide choice of position and great security, thus increasing its efficiency. Even if at the beginning the cavalry commander himself directs the working of the machine guns, the officer commanding the latter will have to act on his own initiative later on, in accordance with the tactical situation of the moment.
GREAT BRITAIN
Organisation.—Great Britain was one of the earliest countries to adopt machine guns, and the Maxim has been in use for the last twenty years. Machine guns are organised in sections of two guns, and a section forms part of each regiment of cavalry and battalion of infantry, who provide and train the personnel.
The organisation is as follows:—
