The California National Guard State Service Ribbon honors California National Guard members who carry out active service on behalf of California in wartime or in a state of emergency declared by the governor.
At nearly 23,000 members, the California National Guard is the largest in the country; it is made up of the California Army National Guard and California Air National Guard. The Army component dates back to the 1849 founding of a state militia, then called the First California Guard; the Air component, based in Sacramento, traces its roots back to August of 1917 when the 115th Aero Squadron was formed to support the United States’ efforts in World War I.
The ribbon is divided into equal thirds of red, blue, and yellow from right to left.
Subsequent awards may be indicated by diamond devices.
