5. The Battle Of Azzano (Captain America: The First Avenger)
https://www.youtube.com/watch?v=XtPIuhF5MvU There was a lot of footage of war in Captain America: The First Avenger - including scenes involving the likes of Bucky Barnes, Dum Dum Dugan and the rest of the Howling Commandoes. This particular scene was omitted from the movie, however, and it shows Barnes, Dugan and Gabe Jones in a foxhole with the U.S. army battling against German soldiers. At that point, a battalion of HYDRA soldiers sent by Johann Schmidt AKA Red Skull arrived. Their weapons were Tesseract-powered and one of the tanks fired upon the German troops, wiping them all out. It then turned on the Allied soldiers and fired on them, prompting the survivors to surrender. They would then be taken to the Austrian HYDRA Weapons Facility to make more Tesseract-powered weapons, where they would be rescued by Captain America in a scene that was actually shown in the movie. Perhaps it would have been better to include this scene to show exactly how they ended up there.
