In military strategy, which term refers specifically to achieving favorable outcomes through active engagement?

The term that specifically refers to achieving favorable outcomes through active engagement is "compel." In military strategy, to compel means to use force or the threat of force to induce an adversary to act in a desired way. This contrasts with merely influencing outcomes or supporting allies without direct involvement in the conflict.

Compelling an opponent typically involves decisive actions that lead to a change in behavior or strategy, demonstrating a clear demonstration of power or resolve. This can include military actions intended to threaten an adversary's interests or deter them from pursuing certain courses of action.

In contrast, support generally involves aiding allies or partners without necessarily engaging directly in a conflict. Control refers to the ability to direct or influence a situation, often focusing on managing resources or strategic positioning rather than direct engagement. Influence, while related to shaping perceptions and decision-making, does not imply the same level of direct action as compelling does. Thus, when considering the goal of achieving favorable outcomes through direct and active measures, "compel" is the most appropriate term.
