How does the hierarchical rank system in Amestris armed forces work? A lot of ranks are mentioned in the world of Fullmetal Alchemist (such as Colonel Mustang, Major Alex Louis Armstrong, etc.) but I've never known, what do these mean compared to themselves.

Can I find a descending order of all the character who's appearing in Fullmetal Alchemist (both in 2003 and 2009 series) with an order according to the rank in the army?
This is compiled/arranged from here and here.
