Major Commands are the primary organizational units in the United States Air Force (USAF) that oversee specific areas of operations, training, and support. Each Major Command is responsible for a distinct mission, such as air combat, logistics, or training, and they help ensure that the USAF meets its strategic objectives. There are several Major Commands, including Air Combat Command (ACC), which focuses on combat operations, and Air Mobility Command (AMC), responsible for airlift and refueling missions. These commands play a crucial role in maintaining the readiness and effectiveness of the USAF in various global scenarios.
