After a fight with a drunk Tony Stark, his friend, Jim Rhodes took the Iron Man MK II armor he used in battle to an Edwards Air Force Base, Rhodes promptly turned it over to the U.S. Military for further investigation. It was modified for combat applications by Justin Hammer.
This new version of the War Machine armor was created by Tony Stark in order to restore the original War Machine armor to its Iron Man MK II form, taking away any trace of Hammer technology.
The armor was later repainted in American flag colors similar to the Iron Patriot.
