In the Italian wiki an user has created a page of "Supreme" Knight Commander. In his opinion, this Commander was seen only in the episode "The Search For Halsey" with Eroic difficult or greater. It's more purplish and with more decorations. This "rank" really exist? I don't play the spartan ops so I don't know it; I don't think. Sorry for my English. --Xwx (talk) 15:17, 5 May 2013 (EDT)
