Captain America: The Winter Soldier
Rumlow and the Strike team, accompanied Captain Rogers and agent Romanoff on a mission to the Indian Ocean to rescue a S.H.I.E.L.D's ship the Lemurian Star from the Algerian pirate Georges Batroc. After the mission, Nick Fury became suspicious of Project Insight, which unknown to him was HYDRA's plot to use a fleet of Helicarriers to kill millions of individuals targeted by an algorithm designed by Arnim Zola to select potential threats to global stability. Once the Winter Soldier (apparently) killed Fury, Alexander Pierce, the highest-ranking HYDRA agent within S.H.I.E.L.D, had Rumlow and Strike spearhead the operation to bring in Steve Rogers. However, a surprise attack on Rogers in an elevator at the Triskelion failed, allowing Rogers to get away. Strike were later able to capture Rogers and his comrades Natasha Romanoff and Samuel Wilson after a fight with the Winter Soldier, although the three were again able to escape captivity with the help of Maria Hill. During Rogers' attack on the Insight Helicarriers, Rumlow attempted to stop Natasha and Fury, only to encounter Sam Wilson. The two engaged in a visceral fight, ending in Wilson escaping from a window as a Hellicarrier rammed into the Triskelion, destroying the building. Rumlow was recovered by paramedics, badly burned and wounded.
