Re: War Machine during TA?
As explained in a recent prequel comic, that's supposed to be official, Tony had sent Rhodey out to investigate an attack by the Ten Rings terrorists in Hong Kong. While he was there, War Machine also ran into a hi-tech Hammer-issue robo-tank belonging to the US military that had been stolen by Ten Rings.
