In the company the files are placed in two ranks according to height from right to left. Each four files form a squad or group, and the entire company is divided into three platoons (_Züge_). When a platoon consists of more than three squads it is divided into two sections (_Halbzüge_). In the normal formation of the company, the three platoons, each in two ranks,[65] are posted on a line in numerical order from right to left. This formation facilitates firing and in garrison meets the requirements of barrack life, each two squads forming a section (_Korporalschaft_) under a non-commissioned officer. During the campaign of 1866 Prince Frederick Charles gave permission to arrange companies so that friends and relatives could serve together in the same squad or section. A company formed in this fashion would, of course, not look so well on parade as one formed regularly, the men according to height from right to left flank, but it would without doubt give a better account of itself in action. For details of the formation of a company and division into fractions see pars. 82-85, German I. D. R. The squad leaders and the two range finders in each platoon are posted as file closers at facing distance in rear of the rear rank of the company. [65] The number of ranks is intimately related to the rate of fire of the infantry weapon. During the days of slow loading, the necessity of keeping at least a part of the rifles at all times ready for firing led the Imperialists in the Thirty Years’ war (loading was executed by 90 motions) to form their musketeers into sixteen ranks, while Gustavus Adolphus was able to form his infantry into six ranks owing to the greater loading facility of their rifles. In the Seven Years’ war the Prussian infantry was formed in three, that of the Austrians in four ranks, the fourth rank serving as a reserve. The first rank fired kneeling. The British infantry was the first to adopt the two rank formation for fire action, forming into four ranks for shock action and frequently for warding off cavalry attacks. Emperor Napoleon considered a third rank useless for fire and shock action and initiated the double rank formation on the eve of the battle of Leipzig. In 1888 the Prussian infantry--the last to do so--gave up the three rank formation which had long since lost its importance in battle and which was retained side by side with the double rank formation for purposes of parade only.
