For OPLANs, what refers to personnel and equipment engaged in direct combat activities?

The term that describes personnel and equipment engaged in direct combat activities is "Combat." This encompasses the various military forces and their respective assets that are actively involved in fighting operations. Combat units are specifically organized, trained, and equipped to carry out offensive and defensive operations against adversaries, making them distinct from other support functions that may be part of a broader operation plan.

In contrast, base operations primarily involve the management and maintenance of the facilities and support structures that sustain military activities, which does not directly involve combat. Operational support includes activities that assist combat operations but are not engaged in the fighting themselves, such as logistics and intelligence roles. Strategic analysis pertains to the assessment and planning of long-term military strategies and does not directly relate to the execution of combat activities. Therefore, the distinguishing feature of "Combat" is the direct involvement in fighting, setting it apart from the other concepts.
