After learning, Plate mail is pretty awesome, especially against lots of arrowfire. However I did get to see how platemail was developed to try and survive bullets. The results were interesting to say the least with more concentration on the vitals, as it as accepted that it was impossible to protect every part of the the user.
Now, the real question I have is how did scale armor and padded stuff fare against arrows?
And I just saw some stuff on the Roman klivanion hence why I wanted to know about the question above
