 of a division. This is best illustrated by doubling or trebling a plane area when both length and breadth have to be equally increased.

The maximum frontage to be covered in attack by the firing line of a company is fixed at 150 m., in order that the density and fire power of that line may be constantly maintained during a prolonged and costly action. During shorter (i.e., rear guard actions), or less costly actions (defense), it is, however, permissible to exceed this limit. The regulations by no means insist upon a literal interpretation of this paragraph, since they mention the deployment of the entire company, when it would certainly occupy a front of about 200 m. There is no disguising the fact, however, that, when extended on a front of 200 m., it is out of the question for the company commander to lead his men.

The regulations do not fix the combat frontage of a battalion, as it depends upon the tactical situation, and the battalion commander is at liberty to place one, two, three, or four companies into the first line. The frontage of a battalion would thus be 300 meters when making an independent attack, and not exceeding 600 meters when fighting a purely defensive action as part of a larger force, in other words, a mean frontage of 400 meters.

This is also true of the regiment. The combat frontage of a regiment acting alone, will, at the start, seldom exceed that of two battalions deployed abreast. From this we obtain a frontage of 600-800 m. for the regiment when it is acting independently, and a frontage of about 1200 m. when it is fighting a purely defensive action as part of a larger force.

Military history tells us that an army corps consisting of 25 battalions, acting as a part of a larger force in a deliberately planned attack, occupies an average front of 2.5 to 5 km. According to this, the frontage of a brigade would amount to about 800-1000 m., i. e., to 6-7.5 rifles per meter of front.
