In The Falcon and the Winter Soldier and the Marvel Cinematic Universe movies, it’s clear that Sam Wilson and Bucky Barnes both picked up several moves from their mentor, the original Captain America, Steve Rogers. Bucky is introduced in Captain America: The First Avenger as Steve’s best friend, who is tragically lost during a mission, but the evil Hydra organization saved him in order to turn him into a brainwashed super soldier. Bucky debuts as the Winter Soldier in Captain America: The Winter Soldier, where he is eventually able to break free from Hydra’s mind control.
Sam Wilson, a.k.a. Falcon, is also introduced in Captain America: The Winter Soldier as an Air Force veteran who befriends Steve. Their efforts to help Bucky cause major conflict in Captain America: Civil War, but the trio form a solid bond and take their leave from the Avengers team before being pulled back in by the events of Avengers: Infinity War and Avengers: Endgame. At the end of Avengers: Endgame, an elderly Steve Rogers then passes the mantle of Captain America onto Sam, with Bucky’s approval.
The Falcon and the Winter Soldier on Disney+ focuses on Sam Wilson and Bucky Barnes in a post-Steve world. It’s clear their friend and mentor had a huge effect on them, and this comes across in their move sets. The time that they spent together in the films mentioned above and especially the time between each feature gave them plenty of time to train together. In general, the three have similar fighting styles, but throughout the Marvel films and The Falcon and the Winter Soldier, Sam and Bucky display a few distinct feats that they must have picked up from Steve.
Steve, Sam, and Bucky each handle the iconic vibranium shield several times. In addition to using it for its intended purpose, as a shield, they all learn how to use it in a variety of other ways. In Captain America: The Winter Soldier, Bucky shows that he is adept at catching the Captain America shield with his metal arm and throwing it back at Steve. He repeats this, as he catches the shield several times over the course of The Falcon and the Winter Soldier too. Sam spends an entire training montage in The Falcon and the Winter Soldier, episode 5, “Truth” learning how to consistently throw and catch the shield. Sam also flips the rounded shield back up into his hands by stomping on one edge of it, something Steve also did, notably at the end of the elevator fight scene in Captain America: The Winter Soldier.
