The Joint Concept for Entry Operations describes in broad terms the vision for how joint forces will enter onto foreign territory and immediately employ capabilities to accomplish assigned missions. This includes conducting entry in the presence of armed opposition characterized by increasingly advanced area denial systems as well as where the environment and infrastructure may be degraded or austere. JCEO describes the broad range of purposes for entry operations that expands this challenging set of military operations beyond the more limited scope that exists in current joint doctrine which is focused on forcible entry. Coupled with the challenge of gaining and maintaining access, operating in the presence of sophisticated missile, cyberspace, and potentially WMD armed opponents, these operations will stress the future joint force when called upon to deter or defeat aggression on foreign territory. Therefore, this concept reviews the problem of entry operations and offers key ideas to solving this set of obstacles to effectively projecting force in such situations. Each Service has a vital role in ensuring that we can successfully conduct entry. This concept was developed with representation from each of the Services and from across the Joint Staff in coordination with the combatant commands, multinational partners, and other key stakeholders. The need for maintaining our ability to enter foreign territory, when directed by the national command authority, is clear. Once access is achieved, we must be able to accomplish all assigned missions ashore, both in the littoral regions and further inland. The Joint Concept for Entry Operations is a critical step in ensuring that the joint force retains the ability to do so.
