War Machine

Real Name: James "Rhodey" Rhoades

James Rhoades is Tony Stark's best friend, and holds the rank of Colonel in the U.S. Air Force.  Stark designed a battle suit for Rhodey similar to the Iron Man armor, but trading superior firepower for fewer sensors and other non-combat related options.  Two of the main differences are the rocket launcher and the heavy-caliber Vulcan cannon mounted on the War Machine's shoulders, allowing the War Machine to deploy an impressive array of sheer firepower.
