The Director will then read the Situation aloud, point out the places mentioned where practicable and make such explanations as may be necessary.
_The Director_: “Lieutenant Williams, the situation states that the 10th division is operating on a certain sector. What do you understand by that?”
_Lieutenant Williams_: “It is the area lying between the two designated boundaries which has been allotted to the division and to which, in general, the division confines its operations. As I understand it there is a division on our right and another on our left. If each were not given a definite area to operate over I can readily see how there might be great confusion over the question as to just who is responsible for a certain area. By assigning definite boundaries this question is eliminated. The division assigned to the particular sector is responsible for everything in the sector.”
_The Director_: “Captain Hastings, what do you understand by the term attacking brigade?”
_Captain Hastings_: “It is the term used to designate the Brigade that is leading—the brigade that is making the attack against the enemy—as distinguished from the brigade that is held in reserve.”
_The Director_: “There are several ways of disposing the infantry of a division for combat. I will outline them briefly in order that you may see what the formations are and the relation that our battalion has to them.
“The division may be deployed with the two brigades side by side, each brigade being echeloned in a column of regiments. The leading regiment of each brigade is in turn echeloned in a column of battalions, one as assault, one as support and one as local reserve. The second regiment (less 1 battalion) of each brigade forms the brigade reserve. The remaining battalion from each of these regiments is held out by the division commander as a division reserve. In this case the division commander is driving a two unit team with the units abreast. Under exceptional circumstances the division may be deployed with the brigades side by side with all four regiments in line each echeloned in a column of battalions. This formation uses up a division very rapidly and is only employed where an exceptionally wide front has been assigned.
