7. The Howling Commandos
The Howling Commandos made a brief appearance in Captain America: The First Avenger, but their role was mainly summed up in a montage. This is a shame, because Dum Dum Dugan and the rest of the elite special unit are quite the band of characters. If the Agent Carter short proves to be a success, perhaps Marvel could do another period piece featuring the Commandos? The Captain America montage shows that they work side by side with Cap through several missions, and it would be easy to set the One Shot within that timeframe. It would also be just as interesting to see the team
after Cap gets frozen in ice, in a mission of their own. In the comics, there are even modern versions of the team, so perhaps the short film could go in that direction? Either way, this team is just too cool not to feature again in the MCU.
