Sustaining U.S. Global Leadership: Priorities for 21st Century Defense requires the Joint Force to successfully project power despite anti-access/area denial (A2/AD) challenges. Guided by the Capstone Concept for Joint Operations: Joint Force 2020 (CCJO: JF2020), and directly supporting the Joint Operational Access Concept version 1.0 (JOAC), this concept describes how the Joint Force will conduct entry operations in support of a broader national approach. It focuses on operations in hostile and uncertain environments where opposition is possible or expected, and where such opponents may possess advanced area denial capabilities. In opposed as well as unopposed operations, geographic and infrastructure impediments may significantly inhibit the deployment and entry of joint and multinational forces into an operational area. As a result, most of the required capabilities articulated by this concept can also be used to conduct entry in degraded or austere environments where opposition to entry operations does not exist. Finally, while overcoming anti-access threats in getting to the theater is required, it does not eliminate the need to continue to defend against these threats while overcoming area denial challenges during and after entry.
