War Machine

I just popped a 4* war machine and was like, oh I completed the get a 4* avenger thing. Then I check, and he isn't an avenger! So is he not an avenger in the comics, or is there something I don't understand here. Thanks for any advice.

You actually have a better case from his time in the comics as Rhodes has time as both Iron Man and War machine in the comics.
Sense made!
