These are, without doubt, Slayers, but don't ask me if they're Troll Slayers or a higher rank. Slayers are dwarves who lost their honour, so they take off their armour, dye their hair orange and go out to die in battle against the most gruesome monster they can find. The longer they survive the longer their hair gets, so these two are definitely not the lowest rank.
