c. Battalion sections. (1) Each battalion section consists of vehicles of the transportation platoon that serve the battalion (h below) and the following personnel:
Section leader (battalion supply officer).
Section sergeant (battalion supply sergeant).
The section leader becomes battalion supply
officer during periods of tactical training and in op- erations when the battalion supply echelon is oper- ative. (See par. 3c(2).) When not acting as bat- talion supply officer, he is responsible to the platoon leader for the training and operation of his section. As battalion supply officer, he commands the am- munition and the kitchen and baggage components of the section (battalion trains) except while they are under regimental control. When his duties re- quire his presence elsewhere, the command of these vehicles may be delegated to the battalion motor transport officer or to an assistant of the battalion supply officer. For his duties as battalion supply officer, see paragraph 5 and FM 7-20.
(3) The section sergeant is the principal enlisted assistant of the section leader. He becomes battalion supply sergeant when the section leader performs the duties of battalion supply officer; as such, he works in the battalion area under supervision of the battalion supply officer. He may be directed to ac- company parts of the battalion section of the trains when deemed advisable.
