Ready to Comply - Bucky Barnes

1943, Steve's new addition to the Howling Commandos, a while after Barnes died, known to be one of the best spies out there, spending most time on learning as many things as she can. Sienna Orlovschi, what could go wrong in participating in the war?
The worse case scenario, she dies, but there was a possible outcome that would've led her to want to die. HYDRA, Hitler's corrupted twin, tail of the devil, Johann Schmidt, their leader, the 'superior man'. Sienna meets her new 'friend', he is called Winter Soldier, or, thats what HYDRA calls him.

What could be worse then death?
