Which of the following is a significant capability of close air support?

Close air support (CAS) primarily provides ground forces with the ability to engage and neutralize enemy positions in close proximity to friendly troops, making the variety of attack a significant capability. This includes the use of different types of munitions and attack profiles that can adapt to the specific tactical situation, whether that be precision guided munitions for high-value targets or more area-effect ordinance for engaging larger troop formations or vehicles. The flexibility in the types of attacks allows ground commanders to tailor their air support to the operational needs of the moment, enhancing the effectiveness of ground operations.

In contrast, while extended range of operations, logistical support, and heavy armored deployment are important aspects of military planning, they do not specifically define the primary function and advantage of close air support in the same way that the variety of attack does. CAS is fundamentally about direct engagement and support of ground forces, which is best exemplified by the capability to deliver a wide range of air-to-ground attacks effectively.
