Final answer:
The term 'Subordinate Campaign' refers to plans that are designed to support and align with overarching strategic goals in military or organizational operations, ensuring efficiency and unity of effort towards the mission. Hence, option (C) is correct.
Step-by-step explanation:
Subordinate Campaign plans are synchronized with a farther-reaching plan to enhance the efficiency of execution if they are required to complete a given mission. These plans are typically components of comprehensive military strategies or large-scale organizational objectives, where execution details are refined at lower levels to align with overall goals and directives.
In the context of military operations, for example, a subordinate campaign might be planned in a way that ensures it supports the broader strategic goals of the theater commander. This coordination ensures that all units are moving in unison towards the shared objective and that resources are utilized optimally.
