What is it? Joint interdependence is the meaningful reliance on other service and joint capabilities to maximize their complementary and reinforcing effects while minimizing service vulnerabilities. Each branch of the Armed Forces excels in a different domain - land, air, sea, space and cyber. Army Joint interdependence ensures that our systems are fully complementary with the other Services to generate a synergy that creates overwhelming dilemmas for opponents. Operational experience affirms a future that is irrefutably joint, and the Army conducts its transformation activities in terms of capabilities the Army can build to support the joint force commander.
What has the Army done? The Army´s transformation efforts are focused on Joint Capability Areas (JCAs) currently under development. Under Joint Staff lead, these JCAs are being developed by Functional Capability Boards, Combatant Commands, and the Supporting Services. JCAs are intended to provide a common capabilities language for use across Department of Defense (DoD) activities and processes. The Strategic Planning Guidance for 2006-2011 directed a Joint Force Capabilities Assessment to "identify and organize the capabilities required for the Defense Strategy." The resultant study identified 21 high-level JCA which were endorsed by the Secretary of Defense in May 2005, with direction to incorporate JCA language in future key defense documents. The Army's concept development and experimentation program continued to conduct combined investigations with United States Joint Forces Command (USJFCOM) and sister services to refine concepts and required capabilities for the future joint force, including wargames and experiments such as Joint Urban Operations, Unified Quest, and Urban Resolve.
What efforts does the Army plan to continue in the future? Because our new modular formations will operate in joint, multinational and interagency environments, these formations are designed to enhance joint concepts for battle command, fires and effects, logistics, force projection, intelligence, air and missile defense. Our joint training opportunities will continue to improve as we continue to support the Joint Forces Command development of a Joint National Training Capability. The planning, scenarios, connectivity and overall realism we are working to create will enhance critical joint operations skills for commanders and Soldiers. The Army will continue to partner with USJFCOM and other services to support joint concept development and capability assessments developed by USJFCOM and approved by CJCS.

Why is this important to the Army? The Army is aggressively working with the other Services to improve the ability to dominate across the entire range of military operations. Our efforts embrace two characteristics of modern warfare. First, technology has extended the reach of modern weapon systems to the extent that collective force protection and anti-access techniques are necessary, even in facing irregular, asymmetric challenges. Second, the other Services' capabilities to dominate air, sea and space have direct impact on ground forces' ability to dominate on land. Without this capability we increase the vulnerability our Soldiers face against an adaptive enemy.
