Which supply class encompasses repair parts for vehicles?

The correct choice is associated with supply class VII, which encompasses major end items, including repair parts for vehicles. This classification covers items that are used to repair and maintain military equipment, ensuring operational capability. Repair parts are essential because they allow for the upkeep and functionality of vehicles, making it possible to maintain valuable assets in the field.

Supply class II generally covers clothing and individual equipment, supply class III pertains to petroleum, oils, and lubricants, while supply class V includes ammunition. Therefore, these classes do not relate to the repair parts necessary for vehicles, which is why class VII is the appropriate classification for understanding the logistics and supply chain related to military vehicle maintenance.
