| Term | Definition |
|---|---|
| Concept of Operations | a verbal or graphic statement that clearly and concisely expresses what the commander intends to accomplish and how it will be done using available resources |
| Operational Art | the cognitive approach by commanders and staffs—supported by their skill, knowledge, experience, creativity, and judgment—to develop strategies, campaigns, and operations to organize and employ military forces by integrating ends, ways, and means |
| Army Design Methodology (ADM) | a methodology for applying critical and creative thinking to understand, visualize, and describe unfamiliar problems and approaches to solving them |
| Defeat | to render a force incapable of achieving its objectives. Defeat has a temporal component and is seldom permanent |
| Defeat Mechanism | a method through which friendly forces accomplish their mission against enemy opposition. Army forces at all echelons use combinations of four defeat mechanisms: destroy, dislocate, disintegrate, and isolate |
| Destroy | a tactical mission task that physically renders an enemy force combat-ineffective until it is reconstituted |
| Dislocate | to employ forces to obtain significant positional advantage, rendering the enemy’s dispositions less valuable, perhaps even irrelevant |
| Disintegrate | to disrupt the enemy’s command and control system, degrading its ability to conduct operations while leading to a rapid collapse of the enemy’s capabilities or will to fight |
| Isolate | to separate a force from its sources of support in order to reduce its effectiveness and increase its vulnerability to defeat |
| Physical Effects | those things that are material |
| Temporal Effects | those that occur at a specific point in time |
| Cognitive effects | those that pertain to or affect the mind |
| Stability mechanism | the primary method through which friendly forces affect civilians in order to attain conditions that support establishing a lasting, stable peace |
| Four Stability Mechanisms | compel, control, influence, and support |
| Compel | to use, or threaten to use, lethal force to establish control and dominance, affect behavioral change, or enforce compliance with mandates, agreements, or civil authority |
| Control | involves imposing civil order. Influence means to alter the opinions, attitudes, and ultimately the behavior of foreign friendly, neutral, adversary, and enemy audiences through messages, presence, and actions |
| Support | establishes, reinforces, or sets the conditions necessary for the instruments of national power to function effectively |
| End State | a set of desired future conditions the commander wants to exist when an operation ends |
| Center of Gravity | the source of power that provides moral or physical strength, freedom of action, or will to act |
| Decisive Point | a geographic place, specific key event, critical factor, or function that, when acted upon, allows commanders to gain a marked advantage over an enemy or contribute materially to achieving success |
