What are the components of the "Decisive Action" model?

The correct answer identifies the components of the "Decisive Action" model as offense, defense, stability operations, and defense support of civil authorities. This model encompasses the full spectrum of operations that Army units may engage in to achieve mission success.

Offensive operations focus on defeating the enemy, while defensive operations are about protecting one's forces and assets. Stability operations involve efforts to maintain or restore order in a volatile environment, essential for rebuilding and fostering stability post-conflict. Lastly, defense support of civil authorities highlights the military's role in supporting civilian agencies during crises, showcasing the Army's flexibility and commitment to a whole-of-nation approach.

In contrast, other choices provide either incomplete aspects or different operational focuses that do not capture the complete framework established by the Decisive Action concept. Recognizing these four components is crucial for understanding how modern Army operations are structured and executed, which is vital for effective mission planning and execution.
