"Men-at-Arms" refers to soldiers in the medieval period who were heavily armored and trained for combat. They typically fought on horseback and were often part of the nobility or elite military units. Their equipment included a helmet, breastplate, and various weapons such as swords and lances, making them formidable opponents on the battlefield. These warriors played a crucial role in feudal societies, serving their lords in exchange for land or protection. The term is also associated with the Knights, who were a specific class of men-at-arms known for their chivalric code and ceremonial duties, as well as their military prowess.
