Siege Combat is a subset of Armoured Combat that involves the use of siege engines, such as onagers, trebuchets, scorpions, ballistae, and the like.
Siege Combat is only done during melee combat situations; it is not used in single combat. It is most commonly employed when Ealdormere goes to War at Pennsic, but some events do allow Siege weapons at home.
Siege engineers are required to wear armor, since they are on the battlefield and may have encounters with fighters, combat archers, or even missiles from opposing siege engines. They train in the use of their machine, and inspect it and the ammunition before each battle.
In Ealdormere, a fighter must have their primary authorization in One-handed weapon and shield before they can get a Siege authorization.
