Resolute Support Mission - Afghanistan - SSI X 300 Classic License Plate

The "Resolute Support Mission" (RSM) was a non-combat NATO-led mission in Afghanistan launched on January 1, 2015, to train, advise, and assist the Afghan National Defense and Security Forces (ANDSF). It succeeded the International Security Assistance Force (ISAF) and ended in early September 2021. While "SSI X 300" is not a standard term associated with the mission, the acronym "SSI" could be a typo or a specific internal designation. The history of the mission is its transition from ISAF to focus solely on institutional capacity building for the ANDSF.
