Before I start this is based on Call of Duty Modern Warfare 2... BUT CoD is also a comic book here's the link so you know i'm not lying.

First I'm gonna start with with the main character
Task Force 141-
either Sam Worthington as Captain McTavish
or Christian Bale as Captain McTavish
Come on both look like him could pull off an english accent and are good in war
type movies.
Paul Bettany as Simon "Ghost" Riley
Liam Neeson as Captain John Price
I am I the only person that would love to hear "What the hell kinda name is Soap?" coming from Liam Neeson :P
Til Schweiger as Nikolai
Tahmoh Penikett as Scarecrow
Burn Gorman as Meat
Right now I've only done the good guys but I'll update it when i have time and add in the villains.
