Mountain warfare presents such difficult problems to troops, requires a sum total of endurance, energy and intelligence, physical qualifications and special familiarity, that neither every recruit nor every unit of the army will quite fulfill all its demands, although the experience of Suworov, during his campaign in the Alps, apparently contradicts this statement. Many disadvantages can be neutralized by peace training and discipline, of course, but training alone will not suffice. For overcoming the difficulties peculiar to mountain warfare, a suitable equipment permitting free movement, and at the same time ensuring the comfort of the men while at rest, is necessary. The lack of such mountain equipment is keenly felt even during short exercises lasting only a few days. Even Switzerland plans at present the formation of three mountain brigades. Austria already has special mountain brigades assembled for mountain warfare in its Kaiser-Jäger, Rural Riflemen, and also in the troops of Bosnia and Dalmatia. The Italian _Alpini_ (consisting of 22 battalions in time of peace, to which militia companies are attached on mobilization, and which have in addition a reserve of 22 territorial companies) form a selected corps which is doubtless capable of accomplishing excellent results. The Italians propose to attach machine guns to these units. It is worthy of note that these troops carry explosives. In France the troops garrisoned in the Alpine districts are divided into thirteen groups, each consisting of one battalion, one mountain battery, one engineer company, and machine guns. As modern fire effect makes it impossible for mounted officers to direct the firing line, it was natural to use the more improved means of communication, the telephone and telegraph, in addition to the visual signals employed by the navy. The improvements made in weapons have had a further influence on the transformation of the infantry. Even a small force of infantry can with its magazine fire inflict annihilating losses in a very short time on closed bodies offering favorable targets, especially when this fire is delivered from a flanking position. This requires, on the one hand, that greater attention be paid during combat to local reconnaissance, which can be but imperfectly made by mounted officers with the troops, and, on the other hand, it necessitates the employment of smaller independent detachments for our own security and for harassing the enemy. Intimately connected herewith is the introduction of machine guns, possessing great mobility, which enables them to take advantage of rapidly passing moments for pouring a heavy fire on the enemy and also for reinforcing the independent cavalry in advance of the army.
