Infantry, as will be seen in the historical portion of this work, used to be of various natures, such as Guards, Grenadiers, Fusiliers, Rifles, and Light Infantry, which still survive, but as names only. Napoleon said he wanted but one sort of Infantry, and that _good Infantry_. This aspiration may now be realized. All Infantry, however designated, is of one kind only, and works in the same manner in war. The formations of Infantry are the _Company_, the _Battalion_, the _Regiment_, and the _Brigade_. THE COMPANY The Company, with its three officers--Captain, Lieutenant, and Ensign--and its Sergeants and Corporals, has been for centuries the foundation stone of the organization of Infantry. Its Chief, the _Captain_, is the officer with whom the men are most intimately associated, as he is responsible not only for their drill, discipline, and training, but also for their food, clothing, pay, and lodging. The men’s confidence in their Captain is grounded on this responsibility. It is to him that they learn to look for their well-being, comfort, and redress of grievances, as well as for praise or blame. The Captain is thus in daily contact with the men, and learns to know them, and be known by them. His influence with his men, owing to these personal relations, is the keystone of command and discipline, and makes him their natural leader in action. To avoid repetition, it may be here mentioned that the same remarks apply to the _Squadron_ and _Battery Commanders_, who, in the Cavalry and Artillery, hold the same position with regard to their men as the Captain does in the Infantry. The Company is usually divided into _Half-Companies_, commanded by a Lieutenant, and into four _Sections_, each under a Sergeant; but the German Company has three Sections under a Lieutenant. The tactical movements of a Company in action are usually carried out by Sections. THE BATTALION The Battalion of 1,000 men is universally recognized as the Tactical Unit of Infantry. Operations are ordered, carried out, and recorded by Battalions. The Battalion is in modern armies provided with transport to carry its ammunition and entrenching tools, as well as its baggage and immediate supply of food, so as to render it independent. The Battalion is commanded in foreign armies by a Major or his equivalent, but in the British and Russian Services by a Lieutenant-Colonel. The Battalion Commander is assisted by a Staff Officer, styled his _Adjutant_, and by a small Administrative Staff. The number of Companies in a Battalion is, in the British Service, eight, with 3 officers and 120 men each, but in other armies four, with 4 or 5 officers and 240 men.
