What, in full armour? Haven’t I been told numerous times that what we think of as a “knight’s armour” usually makes it hard to impossible to move around unless on horse? These look like a pain to even get up.

(The text is infuriating, it looks just familiar enough to make me think I could read and with a bit of effort understand it if they simply used a different, less quirky font)

Edit: apparently some people take issue with me being confused and asking a question to see what I misunderstood. Nice.

Moving around is fine - you can run, jump, spin, do whatever you like, in full armor like that. It’s something like ~30 pounds, which is bad, but not deabilitating,

The issue that arises is fatigue - it’s horrible to make a march in, and takes time to take on and off. So while there would often be a core of heavy infantry outfitted like this, most infantry would prefer lighter armor.

The only armor that would be legitimately unable to be used on foot would be jousting armor, which was immensely heavy because it was meant to protect the user entirely during sport (the, well, joust).
