The 90th Military Operations Research Society Symposium will once again be an in-person event! We are fortunate to have the 90th MORS Symposium hosted by the Marine Corps University in Quantico, Virginia 13-16 June 2022 (abiding to any DoD and COVID-19 guidance and restrictions). The theme for the 90th MORS Symposium is “Innovative Analysts Supporting Integrated Deterrence.”
