Final answer:
The Army's two Core Competencies enable forces to achieve decisive action through intelligence services to defeat external threats and counterintelligence to protect from internal threats, while also enabling strategic planning and adaptation to new technologies and battlefield conditions.
Step-by-step explanation:
The Army's two Core Competencies, according to the referenced materials, highlight capabilities that enable Army forces to achieve decisive action. The Core Competencies refer to using intelligence services to defeat external threats and using counterintelligence services to protect the nation from internal threats. These competencies, when effectively employed, allow the Army to maintain strategic superiority, anticipate and respond to global conflicts, and adapt to new technologies like Artificial Intelligence (AI), as envisioned in the Army 2040 project. Furthermore, the historical context of the early Cold War provides examples of how the army must be agile, with specialized units like Ranger Companies, and integrate long-term planning with the necessity to adapt to changing circumstances on the battlefield. These competencies contribute to an Army capable of not only fighting and winning wars but also managing different elements and harmonizing them for operational success.
