Potential adversaries have studied the operational advantages of the U.S. joint force and as a result are developing A2AD systems and capabilities intended to challenge the U.S. militarys asymmetric advantage by denying freedom of access and maneuver in the global commons and across all warfighting domains. The advancement and proliferation of A2AD capabilities enable adversaries to negate U.S. high valuecapable assets by holding critical forward infrastructure at risk and imposes a cost imposition that could prove prohibitive. Sustained and integrated efforts across the joint force are required to ensure the continued U.S. and allied access to, and maneuver in the global commons. Well defended and mutually supportive Expeditionary Advanced Bases EABs will ensure operational freedom of action by keeping a foot in the door in contested environments. The integration of game-changing technology in force development paired with an innovative offset strategy will enhance the joint forces ability to preserve vital national security interest in contested regions through the employment of well defended EABS supported by a joint force with resilience, capacity, and operational agility.
