Today's Fact
When Washington needed its new Captain America trained fast, it quietly put a skull-masked mercenary on the payroll.
When Steve Rogers refused to take orders from the Commission on Superhuman Activities and handed back the shield, the Commission picked a replacement: John Walker, a super-strong patriot then calling himself Super-Patriot. Walker had the strength and the flag-waving, but not the technique — so the Commission hired trainers. Alongside Freedom Force and the Guardsmen, the faculty included Taskmaster, the mercenary whose photographic reflexes had already banked Rogers' shield-fighting style move for move. In Captain America Vol. 1 #333 (1987), Walker steps into the costume with a supervillain on his teaching staff.
The sessions were specific: Taskmaster's assignment was the shield. He drilled Walker in the throws, the ricochets, the catch on the run — the complete Rogers repertoire, delivered by a man who had acquired it by watching Rogers fight and who normally sold the same lessons to the criminal underworld. Walker's Captain America was, in the most literal sense, a copy of a copy: Rogers' artistry, memorized by an enemy, retaught to a government stand-in.
Walker's tenure curdled fast — brutality on missions, then the Watchdogs murdered his parents, and the experiment ended with Rogers reclaiming the shield. But the training outlived the job. Rebranded as the U.S. Agent, Walker kept fighting with the shield for years afterward, still throwing it the way Taskmaster taught him: the villain's lessons, permanently installed in a government hero.
Why It's Obscure
The star-spangled syllabus had exactly one qualified instructor, and he charged by the lesson.

The borrowed arsenal, the pupil, and the teacher — shield front and center in all three.
