The captain points out in advance the selected position in front of the line occupied. The designated number of each squad moves to the front; the line thus formed preserves the original intervals as nearly as practicable; when this line has advanced a suitable distance (generally from 100 to 250 yards, depending upon the terrain and the character of the hostile fire), a second is sent forward by similar commands, and so on at irregular distances until the whole line has advanced. Upon arriving at the indicated position, the first line is halted. Successive lines, upon arriving, halt on line with the first and the men take their proper places in the skirmish line.
Ordinarily each line is made up of one man per squad and the men of a squad are sent forward in order from right to left as deployed. The first line is led by the platoon leader of the right platoon, the second by the guide of the right platoon, and so on in order from right to left.
The advance is conducted in quick time unless conditions demand a faster gait.
The company having arrived at the indicated position, a further advance by the same means may be advisable. (218)
[256]. Use and purpose of advance in succession of thin lines. The advance in a succession of thin lines is used to cross a wide stretch swept, or likely to be swept, by artillery fire or heavy, long-range rifle fire which cannot profitably be returned. Its purpose is the building up of a strong skirmish line preparatory to engaging in a fire fight. This method of advancing results in serious (though temporary) loss of control over the company. Its advantage lies in the fact that it offers a less definite target, hence is less likely to draw fire. (219)
[257]. Improvised formations. The above are suggestions. Other and better formations may be devised to fit particular cases. The best formation is the one which advances the line farthest with the least loss of men, time, and control. (220)
The Fire Attack
[258]. Advance of firing line; advance by rushes. The principles governing the advance of the firing line in attack are considered in the School of the Battalion. (See [par. 342]–356.)
When it becomes impracticable for the company to advance as whole by ordinary means, it advances by rushes. (221)
[259]. Advancing by rushes. Being in skirmish line: 1. By platoon (two platoons, squad, four men, etc.), from the right (left), 2. RUSH.
