She enters the facility with ease and rescues the future members of the Howling Commandos and Bucky, who has yet to be subjected to Hydra experimentation. However, the group encounters some resistance on their way out, which is the perfect opportunity for Steve to swoop in and use the "Hydra Stomper."
