Please note the spelling of Artillerie as opposed to Artillery, was the elite of the army. By necessity he was a cut above the average, probably educated, intelligent and deliberate by nature. Not for him the mad press of unwashed bodies, the frenzy of clubbed muskets; our gunner took effect from a distance, by virtue of his knowledge of science and his superior intellect.
As with the armies of The Civil Wars, so it is with The Sealed Knot today. There are several specialised units of artillerie, and you don’t have to own a piece to join.
