What caught my eye in the second is how Bucky is swinging far forward from the cable car (to judge by the size of the men inside and outside it), yet is also casually striking a man in that car with his weapon.
And while Cap is much taller than the men in front of him, he's about the same size as the man behind him. And the little guy in green seems to have been standing on the sheer side of the dam until Cap knocked him backward.
