I would have to contest that yet again. True enough that Iron Man was an avenger longer than Captain America, but Iron Man never fought in World War II, which gives Cap the advantage in fighting experience. Fighting for a decade does not necessarily mean that you'll have extensive fighting experience you get from a war. Steve Rogers is a soldier, while Tony Stark is a businessman. You also forget, that instead of the "capucin monkey" you claim cap to be, he is a super soldier, which means all his physical traits are enhanced to peak human. Additionally, towards the end of Civil War, irregardless of who assisted who, this is war. The bottom line is, Cap managed to disable Iron Man. When you're fighting with someone for your life, you don't care what methods you employ, you'd even kick a guy in the nuts to win. That's what we call strategy. If Iron Man is as good as you claim him to be, he would have at least expected that. You don't win battles with power alone, you win with wits.
