The badges for inductees are of a similar design to the sovereign's badge, though without precious stones, and slight differences for each grade. For Commanders, the emblem is gilt with a red enamel maple leaf in the gold central disk; for Officers, it is gilt with a gold maple leaf; and for Members, both the badge itself and the maple leaf are silver. The reverse bears only a serial number, and all are topped by a St. Edward's Crown, symbolizing that the order is headed by the sovereign. These insignia are worn with the order's ribbon, which is blue with golden edges. Commanders wear the badge at the neck while Officers and Members display theirs on the left breast on a medal bar, suspended by, respectively, a bar of gold or silver decorated with a laurel motif. Women in civilian dress may wear their emblems on a ribbon bow pinned at the left chest. The ribbon bar, worn for undress, is the same for each grade, save for a miniature blue cross "pattée" with a maple leaf, the colour of which matches that on the badge of the grade that the wearer was appointed to; someone who has been promoted within the order may wear on their ribbon bar the pins of all grades that they have occupied. These same miniatures also serves as a lapel pin for civilian wear. With the patriation in 1988 of oversight of arms to Canada through the Canadian Heraldic Authority, the constitution of the Order of Military Merit was amended to include the entitlement of all inductees to petition the Chief Herald of Canada for personal armorial bearings, should they not already possess any. Commanders may receive supporters, and all members may have the escutcheon (shield) of their arms encircled with a blue ribbon bearing the order's motto"OFFICIUM ANTE COMMODUM"in gold, and from which is suspended a rendition of the holder's Order of Military Merit badge. For military ranks of colonel and above, recommendations for appointment to the Order of Military Merit are made by a commanding officer or military advisory committee to the Chief of the Defence Staff, who then forwards the name or names to the governor general; per the "Queen's Regulations and Orders for the Canadian Forces", neither the nominee, nor any member of his or her family, can be notified or otherwise made aware that they have been suggested for induction into the order. Nominations are processed by the Advisory Committee for the Order of Military Merit, which is a part of the Chancellery of Honours at Rideau Hall, and has six members: one appointed by the governor general, four by the Chief of the Defence Staff, and the Chief of the Defence Staff him or herself; the Secretary to the Governor General serves as the Secretary General of the Order of Military Merit.
