CSSD-36 3D FSSG MCC 1EZ

CSSD-36 (Combat Service Support Detachment 36) was a logistics unit within the 3rd Force Service Support Group (3D FSSG), United States Marine Corps, based in Okinawa, Japan. Activated during the late Cold War era, CSSD-36 provided critical supply, maintenance, transportation, and medical support to Marine forces deployed throughout the Asia-Pacific region. The unit was instrumental in supporting exercises, humanitarian missions, and contingency operations, ensuring the operational readiness of Marine Air-Ground Task Forces. Its designation later evolved with the reorganization of Marine logistics units, but CSSD-36’s legacy continues within today’s Marine Logistics Groups. The unit’s postal address code "MCC 1EZ" was used for administrative and mail routing purposes.
