SgtMajMarCor is not a rank and even though its billet confers a special rank insignia, the insignia goes hand and hand with its post. Once a SgtMaj leaves the post for another, such as former SgtMaj Alford L. McMichael who went to become Senior Non-Commissioned Officer for NATO, he loses the specialized insignia, but is still a SgtMaj. Regardless of attaining the special billet/ insignia, they are always referred to as SgtMaj. For example even in ceremonies they will be announced as "... Sergeant Major of the Marine Corps, Sergeant Major Barrett."
