Spearmen Sergeants are professional warriors, drawn from the lower classes. They have some skill in combat and are well equipped with long spears, large shields and mail armour. They're very solid defensive companies, able to resist attacks from both foot and horse, so long as they are well supported. If necessary they can form a defensive circle.
