The US Senior Fellows Program offers a distinguished, regionally focused educational experience at the senior service school level for US Army and US Air Force officers holding the rank of Lieutenant Colonel and Colonel. Competitively selected by their respective services, Fellows embark on an intensive 11-month program, engaging in exclusive resident courses and conferences at the George C. Marshall European Center for Security Studies and NATO School, Oberammergau. Fellows with the appropriate qualifications and experience may also serve as co-seminar leaders, contributing to the international academic environment.

Throughout the program, Fellows undertake independent research on strategic security affairs topics, guided by faculty mentors, and present their findings to Marshall Center faculty and leadership. Their research culminates in an advanced research paper, which has the potential for publication in professional and/or academic journals. The program also includes several high-level, in-person engagements with US and NATO commands across Europe, culminating in a "Capstone Field Study" to key institutions and nations within the European theatre.

Through their coursework, research, and interactions with peers in the resident programs, Fellows enhance their broad understanding of international and security affairs and generate a robust network, while gaining specialized expertise in European and Eurasian security challenges. Upon completion, Fellows are eligible for senior service college credit and are well-prepared to serve in strategic regional assignments or as senior staff officers addressing regional security issues.
