Which of the following is a SOF service component command?

The Air Force Special Operations Command (AFSOC) is indeed a service component command of the U.S. Special Operations Command (USSOCOM). AFSOC is responsible for the planning, direction, and execution of special operations missions conducted by the Air Force. This includes a variety of specialized capabilities such as close air support, intelligence, surveillance, reconnaissance, and unconventional warfare.

Being a service component command means that AFSOC falls directly under the command of USSOCOM and works in coordination with other special operations components from different branches of the military, effectively integrating air and ground operations. This command's unique focus on special operations enhances the overall effectiveness of U.S. military capabilities in complex environments, underscoring its vital role within the broader scope of special operations activities.

The other options listed either do not focus on special operations or are not structured as service component commands within the special operations framework.
