The obverse is a silver and
silver-gilt oval
wreath of oak leaves, 55mm high and 37mm wide. Queen Elizabeth II's Royal cypher (EIIR) is in the centre, surmounted by a crown, both gilded. The reverse is plain, with the year of award engraved at the bottom. The dark blue ribbon with a central yellow stripe is attached to a ring on top of the crown, and is finished at the top with a brooch bar bearing the inscription
ARMY EMERGENCY RESERVE. Save for the different ribbon and bar brooch inscription, the award is identical to the
Efficiency Decoration. A clasp, to be worn on the ribbon, was awarded upon the completion of each further period of six years of qualifying service. The clasp is silver and has the Royal Cypher in the centre, surmounted by the Royal Crown, with the year of the award engraved on the reverse. When ribbons alone are worn, a silver rosette is worn on the ribbon to denote each clasp. The maximum number of clasps awarded to any one officer is four. ==References==
