What does the concept of "jointness" imply regarding service capabilities?

The concept of "jointness" refers to the integration and collaborative use of capabilities from multiple military services—such as the Army, Navy, Air Force, and Marine Corps—within a unified command structure. This integration does not occur naturally; it requires proactive and sustained efforts to develop relationships, procedures, and training that enable different services to work together effectively. Jointness is not simply a recognition of the existence of multiple services, but rather an active engagement in cultivating interoperability and synergy among them for more effective operations across various domains, including not just combat but also peacekeeping, humanitarian assistance, and disaster response.

The emphasis on "active development efforts" highlights that achieving true jointness involves implementing policies, training programs, and joint exercises to prepare forces for collaborative missions. This necessitates commitment from both leadership and the personnel involved to ensure that capabilities are effectively synchronized and that communication lines are well established.
