There's no eloquence to Bucky's reply, just a mindless, wordless yell that tears from his throat with a savagery that sounds inhuman even to his own ears; he doesn't let Steve get far, putting himself in Steve's path right away, and pushing back harder than before. This isn't a fight between superheroes. There are no costumes, no props or battle cries. No rules or telegraphed moves. It's a fight between soldiers. Brothers in arms, if not in blood.

Steve's falling into familiar habits, and again, Bucky takes advantage of it, targeting the arm that's not protected by any shield.

"You're rusty."
