It has occured to me that although we never see in writing or spoken of much the ranking structure of the GREEN LANTERN CORPS. In fact the only time we ever hear of it is in the words "Sergeant Kilowog" so for further infomation i'm going to try to make insince of the GREEN LANTERN CORPS ranking system by matching it up to that of the UNITED STATES ARMY ranks; if anyone can think of a corps member and place a rank on them please do so. For now i'm only doing Earths Green Lanterns and a few other from the Corps.

(incase you would need reference: http://en.wikipedia.org/wiki/US_army_ranks#Personnel)

Kilowog Rank: (E9) Command Sergeant Major

Hal Jordan Rank:(W3) Chief Warrant Officer 3 (Note all Honor guard lanterns are Warrant Officers)

Kyle Rayner Rank: (W1) Former Warrant Officer 1 (Kyle is no longer techinally a Green Lantern)

John Stewart Rank: (E7) Sergeant First Class

B'dg Rank: (E4) Corporal

Guy Gardner Rank: (E6) Staff Sergent >>> (W2) Chief Warrant Officer 2 >>> (O7) Bigadier General>>>??? (note: ">>>" means Promotion)

Sinestro Rank: (O5) Ex-Lt. Colonel
