The advance of the attacking troops, under cover of the advance guard, into a preparatory position, is made in such a manner that units are opposite their objectives when the subsequent forward movement against the enemy is begun.[1] This frequently requires a rearrangement of the forces so that even an assailant who is numerically inferior may be superior at the decisive point. A simultaneous attack from the front and flanks requires reserves everywhere and is opposed to the economical employment of the forces; it may easily lead to failure, and is justifiable only when the assailant is greatly superior in numbers or morale.
A premature deployment impairs the leader's influence on the course of the combat and makes it difficult to change the direction of the attack. Route columns, taking advantage of all available cover, will, therefore, be retained as long as possible, and only subordinate units permitted to march directly toward their proper objectives, until the hostile fire compels a more extended deployment (development). The preparatory position is taken up in the last sheltered area in front of the hostile position, provided that that area is large enough to accommodate the attacking force when deployed for action, and to shield it from the observation and the fire of the enemy.
In country generally devoid of cover, infantry will have to be placed in a preparatory position when three kilometers or more from the enemy, even when the latter's artillery will in all probability be neutralized by our own.
"In order to ensure the concerted advance of the various units into the preparatory position, it is advisable, especially in close country, to have them move from one covered position to another. If this is done, units whose march was favored by the nature of the ground, will not arrive prematurely within dangerous proximity of the enemy, while others who had farther to go, or whose advance was difficult, are still a considerable distance to the rear. The leader should make his
