ILE CGSC Common Core Comprehensive Study Guide:
Complete Review of Operational Art, Mission Command &
Joint Doctrine
Question: What is Operational Art?
Answer: Operational Art is 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. It helps commanders understand, visualize, and
describe complex problems and develop a broad operational approach to link
tactical actions with strategic objectives.
Rationale: Operational art is the bridge between tactical actions and strategic goals.
It's the thinking and planning process that determines how a series of battles will
achieve the overall military end state.
Question: What is Operational Design?
Answer: The conception and construction of the intellectual framework that
underpins joint operations plans and their subsequent execution.
Rationale: Operational design is the practical application of operational art. It
provides the structure, logic, and framework (using elements like center of gravity,
decisive points, and lines of effort) to turn the commander's visualization into a
coherent plan.
Question: What are the Elements of Operational Design?
Answer: Termination, Military End State, Objectives, Effects, Center of Gravity,
Decisive Points, Lines of Operation/Lines of Effort, Direct & Indirect Approach,
Anticipation, Operational Reach, Culmination, Arranging Operations, Forces &
Functions, Phasing.
Rationale: These elements are the tools of operational design. They provide a
,common language and framework for commanders and staffs to analyze the
operational environment, visualize the problem, and build an operational approach.
Question: What is a Center of Gravity (CoG)?
Answer: The source of power that provides moral or physical strength, freedom of
action, or will to act. (Doctrine)
Rationale: The CoG is the primary source of strength. It is the hub of all power and
movement, on which everything depends. Defeating or neutralizing the enemy's CoG
is the most direct path to achieving the objective.
Question: What is the purpose of Center of Gravity Analysis?
Answer: To help commanders and staffs analyze friendly and adversary sources of
strength, as well as weaknesses and vulnerabilities.
Rationale: CoG analysis is a critical thinking tool. By identifying the enemy's critical
capabilities, requirements, and vulnerabilities, and doing the same for friendly forces,
planners can identify points of leverage to attack the enemy and protect themselves.
Question: What is a Decisive Point?
Answer: A geographic place, specific key event, critical factor, or function that, when
acted upon, allows commanders to gain a marked advantage over an adversary or
contribute materially to achieving success.
Rationale: Decisive points are not goals in themselves but are the keys that unlock
the door to the center of gravity. They are the intermediate objectives that must be
achieved to generate a decisive impact.
Joint Operations & Strategy
Question: What are the 12 principles of Joint Operations?
Answer: Objective, Offensive, Mass, Maneuver, Economy of Force, Unity of
Command, Security, Surprise, Simplicity, Restraint, Perseverance, Legitimacy.
Rationale: These principles are enduring, fundamental guidelines for planning and
executing joint operations. They are not hard-and-fast rules but rather factors to be
considered in every operation to increase the probability of success.
, Question: What is the purpose of a National Security Strategy?
Answer: To articulate national interest and basic policy direction and intent to the
rest of the world.
Rationale: The NSS is the highest-level strategic document. It communicates a
nation's goals, priorities, and how it intends to use the instruments of national power
to achieve them.
Question: What does "DIME" stand for and how is it used?
Answer: DIME stands for the instruments of national power: Diplomatic,
Informational, Military, and Economic. Achieving national strategic objectives
requires effective unified action, which is accomplished by collaborating,
synchronizing, and coordinating the use of these instruments.
Rationale: The military instrument is just one tool. A comprehensive strategy
integrates all elements of national power to achieve unity of effort and create the
conditions for lasting success.
Question: What is the Unified Command Plan (UCP)?
Answer: A document, prepared by the CJCS and approved by the President, that
assigns missions; planning, training, and operational responsibilities; and geographic
areas of responsibility (AOR) to Combatant Commanders (CCDRs).
Rationale: The UCP is the foundational document for organizing the U.S. military for
global operations. It defines who is responsible for what, preventing gaps and
overlaps in command responsibility.
Army Operations & Doctrine
Question: What is Unified Land Operations (ULO)?
Answer: The Army's overarching operational concept. It describes how the Army
seizes, retains, and exploits the initiative to gain and maintain a position of relative
advantage in sustained land operations through simultaneous offensive, defensive,
and stability operations.
Rationale: ULO is the Army's contribution to unified action. It explains how the Army
thinks about and conducts operations to prevent conflict, prevail in war, and create
conditions for lasting peace.
Question: What are the four foundations of Unified Land Operations?
Answer: Begins and ends with the initiative; Executed through decisive action; By
means of Army Core Competencies; Guided by Mission Command.
Rationale: These four elements are the bedrock of ULO. Initiative provides the spirit,
decisive action (offense, defense, stability) provides the tasks, core competencies
(combined arms maneuver, wide area security) provide the means, and mission
command provides the philosophy of command.
