The US Army War College convened the first of a series of wargames to consider current issues of Senior Leader interest to assess alternative outcomes and potential implications for the US Army. The first wargame in this new series focused on potential Army requirements in the ongoing Syrian conflict. This wargame leveraged the regional expertise of International Fellows as well as faculty subject matter experts and the Army G-35 to derive findings and recommendations to inform senior leader understanding of the conflict. This wargame focused on gaining insights into regional partner equities and reactions that might shape US responses. Participants evaluated alternative scenarios to assess their likelihood and the likely positions their nations would take in each alternative. Unsurprisingly, the most important objective for regional partners was restored regional stability. To that end, a key finding is that regional partners would accept Assad retaining power conditioned on an agreement to a brokered transition of power over time. A smaller number of participants want to see Assad go as soon as possible. These conflicting positions potentially place current US policy at odds with regional partner desires. As such conflicting partner equities represent the potential for friction with any potential US responses. Regional partners did identify roles and missions for US military involvement but they specifically do not desire overt US military actions except to potentially secure Syrian chemical weapons or to increase security cooperation activities. These dynamics indicate a clear requirement for further assessment to inform policy and military decision-making, as well as risk mitigation measures.
