Which of the following is considered a general engineer function?

The correct choice identifies combat engineering as a general engineer function. Combat engineering primarily involves the support of military operations through construction, demolition, and other engineering tasks that enhance the effectiveness of the forces involved. This can include tasks such as building fortifications, clearing obstacles, and creating routes for troop movement, which are integral to military operations and logistics.

In contrast, while menu management, material supply and distribution, and food service management may involve logistical and operational aspects, they do not fall under the definition of general engineering functions. They relate more to administrative, logistical, or culinary management rather than the technical and tactical engineering roles associated with combat engineering. Thus, combat engineering stands out as the only option that aligns directly with engineering principles in a military context.
