Exploiting their old Earth ties to Ireland, the Donegal Guards use a shamrock set on a dark red square as their insignia. On Donegal 'Mechs and vehicles the Guards insignia appears on the right shoulder or side and the insignia of the unit on the left. The regimental insignia is a red rectangle upon which is a crossed hammer and sickle. Per FM:Lyran Alliance, pages 62 and 65.
