Which warriors could be called “special forces” in the medieval Europe?

Answer:

There were no real units in any capacity within Medieval Europe that could be constituted as “special forces” as in most cases soldiers were largely part time. Most soldiers in the Medieval Period were often farmers, butchers, fishermen, and carpenters for most of their life and either volunteered to join the army or were conscripted by local authorities. Although most nobles would be highly trained and well equipped soldiers, again they would not be a permanent fighting force and would spend most of their lives as administrators and rulers of local areas. It is likely that there may have been small bands of trained spies or soldiers whose job was to sabotage enemy siege weapons or supply lines, but these would have been extremely rare.
