Broken People (слэш)

Prompt fill from imaginetonyandbucky: During Afghanistan, the ten rings got frustrated and sold Tony to hydra for hydra weapons and made him the Iron Soldier. After Steve gets Bucky back from Hydra (idk Cap 3 w/ civil war?) Bucky not only remembers the other winter soldiers, but the soldier he fell in love with (Tony) and basically him and Steve go save him (like when they went to Siberia in the movie but none of the "running from the law" stuff)
So I didn’t follow the prompt exactly because there’s already a great story like this on ITAB already and I wrote something similar to it not too long ago (Making a Hero), so I went in a slightly different direction. Instead of Hydra getting Tony from the 10 Rings, they got their hands on him when they assassinated his parents…
