It is obvious that fire action is here indicated, and a preceding paragraph states that mounted infantry will usually accompany the Protective Cavalry, though it is to be doubted if it will be found possible to provide horses for this purpose in time of war. Machine guns, however, will provide the necessary fire power without requiring many men or horses, and the use of a few extra batteries of machine guns with the Protective Cavalry would give them all the stiffening and defensive power of infantry without detracting from their mobility as cavalry. If the Japanese have taught us anything, it is this--that our cavalry, small as it is, if properly supported by strong and well-trained batteries of mobile machine guns, will be able to more than hold its own against greatly superior numbers in a European campaign. To attain such an end we should at once organise cavalry machine-gun batteries, and attach two batteries to each brigade in addition to the guns they already possess. This would give each cavalry brigade the fire power of a battalion of infantry (900 rifles), while in no way detracting from their mobility, as they would only occupy the road space of two extra squadrons, and move just as rapidly over any country. The alternative is to follow Colonel Zaleski’s advice and attach two machine guns to each squadron, which would give the same number of guns, but would be likely to detract from the efficiency of both guns and squadrons. We are, however, dealing with existing organisation, and, however much we may desire to increase the efficiency of our Protective Cavalry, we have only one battery of six guns with each brigade instead of the visionary three. Let us see how we may use them to the best advantage. Supposing the Protective Cavalry to consist of one brigade, they will probably be extended to form a screen over a considerable front. The exact formation and method of advance will entirely depend upon the proximity of the enemy, his strength, and the nature of the country. We will suppose the country open and both flanks exposed and the enemy in the immediate vicinity, the contact squadrons or patrols having gained touch with him. The duties of the Protective Cavalry are the tactical reconnaissance, and the occupation of positions of tactical importance to the infantry and artillery.
