[331]. Issue of extra ammunition when battalion is deployed. When the battalion is deployed upon the initiative of the major, he will indicate whether extra ammunition shall be issued; if deployed in pursuance of orders of higher authority, the major will cause the issue of extra ammunition, unless such authority has given directions to the contrary. (For ammunition supply see [pars. 569]–575.) (294)

Deployment

(See [pars. 456]–462; [463]–466.)

[332]. The following principles of deployment are applicable to attack or defense. (295)

[333]. Avoiding premature deployment. A premature deployment involves a long, disorganizing and fatiguing advance of the skirmish line, and should be avoided. A greater evil is to be caught by heavy fire when in dense column or other close order formation; hence advantage should be taken of cover in order to retain the battalion in close order formation until exposure to heavy hostile fire may reasonably be anticipated. (296)

[334]. Depth of deployment and density of firing line; companies and detachments conducted to their places by their commanders. The major regulates the depth of the deployment and the extent and density of the firing line, subject to such restrictions as a senior may have imposed.

Companies or designated subdivisions and detachments are conducted by their commanders in such manner as best to accomplish the mission assigned to them under the major's orders. Companies designated for the firing line march independently to the place of deployment, form skirmish line, and take up the advance. They conform, in general, to the base company, as prescribed in [Par. 329]. (297)

[335]. Division of battalion into firing line and support. The commander of a battalion, whether it is operating alone or as part of a larger force, should hold a part of his command out of the firing line. By the judicious use of this force, the major can exert an influence not otherwise possible over his firing line and can control, within reasonable limits, an action once begun. So, if his battalion be assigned to the firing line, the major will cause one, two, or three companies to be deployed on the firing line, retaining the remaining companies or company as a support for that firing line. The division of the battalion into firing line and support will depend upon the front to be covered and the nature and anticipated severity of the action. (298)

[336]. Size of support. If the battalion be part of a larger command, the number of companies in the firing line will generally be determinable from the regimental commander's order; the remainder constitutes the support, as prescribed in [par. 335]. If the battalion is acting alone, the support must be strong enough to maintain the original fire power of the firing line, to protect the flanks, and to perform the functions of a reserve, whatever be the issue of the action, as explained in [par. 445]. (299)

[337]. Position of support. If the battalion is operating alone, the support may, according to circumstances, be held in one or two bodies and placed behind the center, or one or both flanks of the firing line, or echeloned beyond a flank. If the battalion is part of a larger force, the support is generally held in one body. (300)
