Which best describes the Air Force's focus on air supremacy?

The Air Force's focus on air supremacy is best described by dominating air operations during conflicts. Air supremacy refers to the condition in which a military has complete control over the airspace above a battlefield, enabling it to operate freely and engage in offensive and defensive missions without significant interference from enemy air forces. Achieving air supremacy is crucial for the success of military operations, as it allows for the protection of ground forces, enhances intelligence gathering, and supports logistical operations. This concept highlights the strategic importance of securing the air domain to ensure victory in warfare, allowing ground and naval forces to operate more effectively and safely.

The other options do not accurately capture this focus. For example, creating a unified land force pertains more to ground operations and collaboration among different military branches rather than the dominance of air power. Reducing military presence overseas suggests a strategic decision unrelated to air superiority and conflicts. Integrating technology with ground tactics focuses on ground operations and does not address the specific goal of establishing control over the air domain during military engagements.
