According to Title 10 authorities, what are the primary military service responsibilities?

The primary military service responsibilities, as outlined in Title 10 of the United States Code, focus on the central functions necessary for maintaining a capable and effective military force. Organizing, training, and equipping forces encompasses the core tasks that each military branch is responsible for to ensure they are ready to perform their missions effectively. This includes structuring units, developing training programs, and providing the necessary equipment to personnel, which are essential for operational readiness.

While inventory and supply management, deploying and sustaining operations, and recruiting and retaining personnel are also important functions within the military, they fall under broader categories or support roles that stem from the foundational responsibilities of organizing, training, and equipping forces. By concentrating on these primary areas, the military ensures that it develops capable, well-prepared units that can respond to national defense needs.
