The last time we see Brock Rumlow is in 2014's Captain America: Winter Soldier, but you'll need to remember him because he makes an appearance. He's the former leader of S.H.I.E.L.D.'s counterterrorism S.T.R.I.K.E. team and is revealed to be a double agent, working for Hydra. He ends up with major wounds in the big battle at the end of the movie, and you see the aftermath in Civil War.
