I don't remember if he was involved in the serum program... that or helping the OSS (early SHIELD) during the War. There's been so little info about this movie. Gah. I do remember reading that he'll have a hand in Steve's improved shield. (Hopefully Tony can upgrade it more in current times.) And I really do feel like there was mention of Howard in some interview helping Steve update the costume. Like Steve does a bit of propaganda in the more traditional suit, but thinks it's sort of silly looking and not practical for a soldier -- and then Howard gets involved to upgrade it.

I want Howard to be a cocky asshole... but not in a lovable way. (To better differentiate him from Tony.) I also want Steve to comment on his drinking.
