(4) Administrative troops are trained in the use of individual weapons, as well as those weapons mounted on vehicles of their units. They are also trained in the tactics and technique of small in- fantry units and impressed with the fact that they are combat troops and must be able to function as such. The personnel available to the service com- pany commander for protection of the train bivouac will vary because of the absence from the area at times of personnel on supply and service activities. The maximum strength will include the personnel of the service company (less the staff section of regimental headquarters platoon) and the rear eche- lon of company headquarters of all companies of the regiment, plus drivers of company transport whose vehicles are in the bivouac area. Weapons include rifles, carbines, antitank and fragmentation gren- ades, antitank rocket launchers, and caliber .50 machine guns.
(5) In preparing plans for the close-in defense of the train bivouac, consideration should be given to both passive and active means and to the several methods for defense that may be adapted to fit the existing circumstances. Some of the means and methods to be considered and integrated into the defense plan are:
(a) Concealment as some protection from all types of attack.
(b) Dispersionof vehicles, personnel, and instal- lations.
