Black Ops might give you a few ideas too if you can find a copy. Not the characters therein mind you (those guys are like 700 points!) but the view of the world from inside one of the big players in the conspiracy wars.
http://www.sjgames.com/gurps/books/specialops/ and some of the other books like it would make good reading too. Would give you a good feel for how capable elite troops can get without getting into the truly superhuman range.
