What did the knights in the military do?

     They were the armed forces on horse back. They all had specific weapons that all knights had hauberk. A helmet to protect there heads from attacks to them.  They also had a shield to block the attacks from enemies. A sword was customarily to the knights was a sword to attack them. These were all things that the knights used in battle plus many more things is what I'm guessing.

     Those such things were possessed by the military. Also by the nobles who were in the military. Which most nobles were a big part of the military. The other class that owned the weapons of knights were the owning class of all these things.Those are some of the things that the knights used to fight in the military.
