Anniversary Quest Problem

So like, HOW does this work, exactly? One of the newer quests is "win ten battles with any rebel admiral in your sqaud."  WHO exactly, is a rebel admiral??? Because regular rebels or even rebel fighters don't count!! So WHO counts??!  Anyone know WHO actually qualifies as one?? Because I sure don't!!!!  Please explain who is a rebel admiral as they don't give sqaut as there is no info or tag
