We've all seen guards in movies walking around with full plate mail, clunking with each step.
Now, I know that plate mail was much more mobile, and much less heavy, than movies and literature imply. But what about the fatigue of wearing that armor for long lengths of time?
How long did guards wear their armor, and how much did they wear? (especially compared to troops and other people of the era).
It might help to contrast between:
If there is such an applicable distinction.
Were there different "levels" of guards? Such as light patrolling guards, but a few heavier guards in reserve?
And how much armor did they wear on a typical day? Did they up-armor during special events? Did they up-armor during a call-to-action / emergency, or just run out there in whatever they had?
As for the specific era: I'm looking for general information, so anything with swords, shields, and armor is acceptable. You'll know the appropriate bounds on timeline better than I.
Thank you for your time.
