Well, when I get up after an evening with Jack Daniels, I bear an uncanny physical resemblance to Tom Sizemore especially before I shave
Seriously, Sizemore has never been given the credit he deserves for his on-screen activity (the less said about his off-screen activity the better). His role has always been as a supporter or in a cast of admittedly better actors and is smothered by their egos and reputations.
Out of the 18 or so Movies I've seen Sizemore in there are three characters from which he could meld performances together and get a pretty good feel for the movie version of Colonel Creedon.
These are:
Lt. Owen Underwood from
Dreamcatcher, an officer who follows the orders of his superiors even if it's exterminating civilians who
may be compromised by Alien influence. Yet morally competent enough to destroy his superiors by blowing up their helicopters if necessary.
Lt.Col. Danny McKnight (a real person)
http://www.dannymcknight.com/index.htm in
Black Hawk Down for command "style".
And last but not least would be Technical Sergeant Michael Horvath from
Saving Privite Ryan for just encapsulating valour.
So I think Sizemore already has some of the most unique insights into what it would take to be me.
