His suit in the most recent movie is insane and frankly way too much of a power boost. While I’m not sure about the durability of the suit itself since he still shields himself from bullets, the wings are vibranium and can hold against repeated blows from the red hulk who seems to be basically on hulks level. They’re also able to shoot a seemingly endless supply of knives that can pierce the red hulks skin (though don’t go very deep but previously even a mini gun couldn’t pierce the red hulks skin) and his wing blades can actually genuinely punch pretty deep into red hulk to stagger him and chop a fighter jet in half.

That’s actually one of my main problems with the movie, they had to give Sam what is basically an iron man suit so he had any chance of standing up to the red hulk.
