[33] _Eskadron_ has been rendered by “troop” in this work. The German _Eskadron_ consists of 4-5 officers, 138-144 men, and 135-139 horses. It is the smallest administrative unit of the German cavalry and is divided into four Züge (platoons). _Translator._ [34] GENERAL MARMONT, in his _Esprit des Institutions Militaires_, p. 41, states that experience has shown that the most suitable strength for a troop is 48 files, divided into four platoons; but, he recommends that platoons should consist of 16-18 files in order to maintain this strength throughout a campaign. [35] _Vorwerke._ While column tactics were in vogue, the above mentioned requirements of a tactical unit were completely fulfilled by the battalion, but this is no longer the case. It is quite impossible for one voice to control the movements of a battalion in action; this is scarcely possible in case of a company. On the other hand, a company is too weak to carry out an independent mission in action. Nothing less than a battalion possesses the requisite fighting power, strength, and capacity for subdivision, to sustain an action independently, to solve minor problems of combat, and to remain a body full of fighting efficiency even after sustaining serious losses such as are unavoidable in every modern infantry action. To attempt a further definition of the term “tactical unit” would be of little value. General von Scherff in a logical manner[36] constructs a “troop unit”[37] from “fighting groups”[38] (squad of infantry or cavalry, or one gun), several of which form a “fighting unit”[39] (company, troop or battery), “possessing the requisite power to carry out a specific task,” and placed under the command of a responsible leader. “The definition of a fighting unit includes, on principle, its indivisibility in action. Dispersion is a crime, division at least an evil.” The “combat unit”[40] consists of a number of fighting units. “The commander of the combat unit (infantry battalion, cavalry regiment, or artillery battalion) should be able to lead it as a compact entity, and should have the power of employing its component parts independently for combined action against some point.” General von Scherff has found imitators in Austria, where the term body of troops (_Truppenkörper_) is applied to an organization having the necessary means for feeding, clothing, and equipping the men, and which is composed of a number of “basic units.”[41] Such “basic units” as can be supervised, handled, and controlled directly by one leader, who knows the individual men thereof and their characteristics, are the troop (_Eskadron_), battery, and company. Von Boguslawski[42] applies the term “fighting unit” to organizations from the company (troop) to the brigade, which act in accordance with the tactics of their arm, supported by the other arms, in the sphere assigned to them by orders or by circumstances. Divisions, which, by the coöperation of the three
