[262]. Formations adopted by support. To enable it to follow or reach the firing line, the support adopts suitable formations, following the principles explained in [paragraphs 249]–255.
The support should be kept assembled as long as practicable. If after deploying a favorable opportunity arises to hold it for some time in close formation, it should be reassembled. It is redeployed when necessary. (225)
[263]. Support controlled by major: size of reënforcement; captain on look out for major's signals. The movements of the support as a whole and the dispatch of reënforcements from it to the firing line are controlled by the major.
A reënforcement of less than one platoon has little influence and will be avoided whenever practicable. (See [par. 353].)
The captain of a company in support is constantly on the alert for the major's signals or commands. (226)
[264]. Reënforcement to join firing line deployed as skirmishers and occupy existing intervals. A reënforcement sent to the firing line joins it deployed as skirmishers. The leader of the reënforcement places it in an interval in the line, if one exists, and commands it thereafter as a unit. If no such suitable interval exists, the reënforcement is advanced with increased intervals between skirmishers; each man occupies the nearest interval in the firing line, and each then obeys the orders of the nearest squad leader and platoon leader. (227)
[265]. Promptness in reënforcing firing line. A reënforcement joins the firing line as quickly as possible without exhausting the men. (228)
[266]. Original platoon divisions to be maintained; duties of officers and sergeants upon joining firing line. The original platoon division of the companies in the firing line should be maintained and should not be broken up by the mingling of reënforcements.
Upon joining the firing line, officers and sergeants accompanying a reënforcement take over the duties of others of like grade who have been disabled, or distribute themselves so as best to exercise their normal functions. Conditions will vary and no rules can be prescribed. It is essential that all assist in mastering the increasing difficulties of control. (229)
