What does air interdiction primarily aim to achieve?

Air interdiction primarily aims to divert or destroy enemy military capabilities to impede their operational effectiveness. This strategy targets enemy supply lines, resources, and capabilities before they can be engaged in combat, with the goal of disrupting their ability to conduct operations. By targeting and neutralizing these elements, air interdiction seeks to weaken the enemy's overall position, making it more challenging for them to launch attacks or defend effectively.

Supporting ground troop advancement is part of a broader set of missions, but it is more directly associated with close air support rather than interdiction. Close air support focuses on assisting ground forces during engagements. The transportation of supplies to allied forces is a logistical operation rather than an active combat strategy, and while it is crucial for maintaining operations, it does not align with the primary objectives of air interdiction. In summary, the focus of air interdiction is on disrupting the enemy's operational capabilities, which is encapsulated in choice B.
