This military study examines the roles and relationships of objectives, effects and end states across the strategic and operational levels of war in order to provide greater clarity for campaign planners. With its inclusion in the recently updated joint doctrine on planning, the effects-based approach to operations attempts to capture the latest insights on warfare. Unfortunately, the new joint doctrine fails to clearly articulate its advantages and scope of applicability, allows inconsistencies internal to itself and with previous doctrine to remain, and causes confusion in formerly well-understood concepts. With the goal of providing a more consistent framework than that offered by joint doctrine, this study, supported by lessons from the Vietnam War, examines why the nesting of objectives, effects and end states must be understood in order to successfully design campaigns to achieve strategic ends. This study attempts to close some existing gaps in joint doctrine. Specifically, it explores the roles and relationships of end states, objectives, and effects across the strategic and operational levels of war. It seeks to show how a more complete understanding of these roles and relationships will enhance joint operation planning, or the "planning activities associated [with] joint military operations by combatant commanders and their subordinate joint force commanders in response to contingencies and crises." Hopefully, it will serve to drive discussion and further innovation. Perhaps it might even provide some practical utility for the planners or doctrine writers who read it. However, in the end, those who disagree with its contents must articulate their counter-arguments, which in and of itself would satisfy the purpose of this study: to provide greater clarity for the military planners who must go forth and develop American military campaigns for the present and future.
