Man-at-armsA man-at-arms was a soldier of the High Medieval to Renaissance periods who was typically well-versed in the use of arms and served as a fully-armoured heavy cavalryman. A man-at-arms could be a knight, or other nobleman, a member of a knight's or nobleman's retinue, or a mercenary in a company serving under a captain. Such men could serve for pay or through a feudal obligation. The terms knight and man-at-arms are often used interchangeably, but while all knights equipped for war were men-at-arms, not all men-at-arms were knights.
Swiss mercenariesThe Swiss mercenaries (Reisläufer) were a powerful infantry force constituted by professional soldiers originating from the cantons of the Old Swiss Confederacy. They were notable for their service in foreign armies, especially among the military forces of the Kings of France, throughout the Early Modern period of European history, from the Late Middle Ages into the Renaissance. Their service as mercenaries was at its peak during the Renaissance, when their proven battlefield capabilities made them sought-after mercenary troops.
CavalryHistorically, cavalry (from the French word cavalerie, itself derived from "cheval" meaning "horse") are soldiers or warriors who fight mounted on horseback. Cavalry were the most mobile of the combat arms, operating as light cavalry in the roles of reconnaissance, screening, and skirmishing in many armies, or as heavy cavalry for decisive shock attacks in other armies. An individual soldier in the cavalry is known by a number of designations depending on era and tactics, such as a cavalryman, horseman, trooper, cataphract, knight, drabant, hussar, uhlan, mamluk, cuirassier, lancer, dragoon, or horse archer.
KnightA knight is a person granted an honorary title of knighthood by a head of state (including the Pope) or representative for service to the monarch, the church or the country, especially in a military capacity. Knighthood finds origins in the Ancient Greek hippeis (ἱππεῖς) and Roman equites. In the Early Middle Ages in Europe, knighthood was conferred upon mounted warriors. During the High Middle Ages, knighthood was considered a class of lower nobility.
