The shield of the X Division MAS represents a particular and less common variant than the better known one of the X Flotilla MAS. The difference lies in the wording reported: the inscription "Division", used after the transformation of the formation into a unit framed in the National Republican Army of the RSI, replaces the term "Flotilla". The shield was made of enameled metal. This variant had a very limited distribution and for this reason it is considered much rarer than the standard version. Today it is a piece that testifies to the organizational evolution of the Decima and represents an element of great interest for specialized collectors.
