The Kierguards are among the best infantry the Ravenstern kingdom can field. They, like all Ravenstern troops, wear their armor with a kilt to cover their legs as a protective measure from the cold of their mountainous homeland. Armed with knight war axes and Ravenstern longswords, they can smash shields almost as well as Huscarls and cut a bloody swathe through lighter infantry. Bearing a recognizable round dragon shield usually seen only in the hands of the highlanders, along with their kilt and helmet, they are rather easy to pick out of a crowd of Ravenstern troops.
Overall, they are essentially a jack-of-all-trades in terms of raw ability for an infantry elite. While they lack a ranged weapon like the Empire Legionnaires, they attack slightly faster than them and often have axes which are far better suited for smashing shields than the Legionnaires' broadswords. On the other hand, they don't have a Fierdsvain Huscarl's staying power and may not always have axes like them , which can leave them somewhat wanting when they have to face a shieldwall. Though they are most assuredly not as fast as D'Shar Ghazi Dervishes, Kierguards are somewhat more durable as their armor provides better protection. They are also one of the cheaper elite infantry forces and make a solid core for any Ravenstern army's infantry component. Unless one is fielding an all-Ravenstern force, other units would be better choices, though if one can't reliably get to those units for whatever reason then you could do worse than the stalwart Kierguard.
This troop is upgraded from Ravenstern Man-at-Arms for 80d and upgrades no more.
