Military ranks of the Second Spanish Republic

Army

Red star

In the Civil War, and following the reorganization of the Spanish Republican Armed Forces, the five pointed red star became an insignia of Spanish Republican Army uniforms.

The new insignia mainly replaced the former eight-pointed and six-pointed silver stars that had been part of the Republican Army officers' uniforms between 1931 and 1936.
