Lieutenants and subalterns are given charge of a troop in the cavalry, a gun or section--according to the number of young officers available--in a battery and of a section of men in an infantry company. Nominally in command of their men, they are in practice largely dependent on their senior non-commissioned officers for the efficiency of the men under their command. An officer’s real efficiency, in peace service, does not begin until he “gets his company” or squadron: in other words, until he is promoted to the rank of captain. Next in grade of rank to the commissioned officers stands the regimental sergeant-major, who is termed a warrant-officer, since the “warrant” which he holds, in virtue of his rank, distinguishes him from non-commissioned officers. He has, usually, sixteen years or more of service; he has even more knowledge of the ways of the regiment than the commanding officer himself, and his place is with the headquarters staff, while his duties lie in the supervision and control of the non-commissioned officers and their messes and training. His position is peculiar; the etiquette of the service prevents him from making close friends among non-commissioned officers, while that same etiquette prevents commissioned officers from making a close friend of him. The only non-commissioned officer who stands near him in rank is the quartermaster-sergeant, who is directly under the control of the quartermaster, and is also a member of the headquarters staff. From this point of rank downward the ways of the different arms of the service diverge. In the infantry, the chief non-commissioned officer of a company is the colour-sergeant, who is responsible both for internal economy and efficiency at drill. In the cavalry and artillery the presence of horses and the far greater amount of equipment involved divide the work that is done in the infantry by the colour-sergeant into two parts. In the cavalry each squadron, and in the artillery each battery, is controlled, so far as drill and efficiency in the field is concerned, by a squadron sergeant-major and a battery sergeant-major, respectively, while the domestic economy of the squadron or battery is managed by squadron quartermaster-sergeant or battery quartermaster-sergeant. Next in order of rank come the sergeants, the non-commissioned equivalent to troop and section officers, but of far more actual importance than these, since parades frequently take place in the absence of the troop or section officer, while the troop or section sergeant is at all times responsible to his superiors for the efficiency of his men. The rank of sergeant is seldom attained in less than seven years, and thus the man of three stripes whom Kipling justly described in his famous phrase “as the backbone of the Army” is a man of experience and fully entitled to his post.
