Which term is used to describe the effectiveness of a military operation?

The term "Measure of Effectiveness" specifically refers to the assessment process that determines how well a military operation achieves its desired objectives. It focuses on evaluating the extent to which the operation meets its intended goals rather than the resources used in executing it. This concept is essential in military planning and execution, as it helps leaders understand the success of their strategies and tactics in accomplishing the mission's aims.

In contrast, the other choices either suggest different assessment facets or lack the specificity required for military operations. For instance, "Measure of Efficiency" pertains more to the resource utilization aspect rather than mission success. "Mission Outcome Evaluation" and "Military Operation Assessment" could be seen as broader terms that might not distinctly capture the specific focus of evaluating effectiveness in relation to the set objectives. Therefore, "Measure of Effectiveness" is the most precise and relevant term in the context of military operations.
