How is a Campaign defined?

A campaign is defined as a series of related military operations that are strategically planned and executed to achieve a specific set of objectives or goals within a broader military strategy. This definition emphasizes the interconnectedness of the operations, where each individual operation contributes to the overall success of the campaign.

In military terminology, campaigns are designed to achieve long-term strategic outcomes, often spanning a significant time period and involving multiple coordinated actions across different locations or domains. For example, during World War II, various campaigns like the Normandy Invasion were part of a larger strategic goal of defeating Axis powers.

The other options do not capture the comprehensive and strategic nature of a campaign. A single military operation, for instance, is limited in scope and does not involve the series of interrelated actions needed to portray a campaign. Similarly, a short-term military engagement is typically more tactical and lacks the depth of planning and execution that characterizes a campaign. An overview of military training programs does not pertain to the operational context of military actions at all, further illustrating the importance of a well-defined campaign as a focused but expansive endeavor.
