"The shield couldn’t have been tactically sound. A red white and blue target on Omaha beach? What was it for? Morale?"
Sergent Baker rubbed his arthritic hands, collecting his words. “No. No. A little bit of morale, but you had it earlier. It was a target. Every bullet that went after him didn’t hit one of our boys." Baker smiled. “And goddamn did they spend a lot of bullets on him."
Baker paused again. “I guess that’s why the Captain’s uniform was red too. So nobody could see how much he bled. Christ."
-Excerpt from an interview with Sgt. Ryan Baker, 1992
In the WTFavengers AU, Captain America was believed to be a man until she was found in 2008. Her gender had been a secret kept by the military the entire war.
Unlike our WWII, their war in Europe dragged on past the Pacific war. Mostly due to the military genius of the Red Skull, who led the massacre at Dunkirk and maintained the Russian-German non aggression pact much longer than in our world.*
Surprisingly, Captain America had to prevent an assassination attempt on Hitler, because if the Red Skull took full control the axis powers would be even harder to defeat and his eugenics programs would have expanded even further.
*Westerners tend to understate how incredibly important Russia was to winning WWII.
