Dwarf Hammerers forms a Dwarf King's personal bodyguard, chosen by the King himself. They are individuals from different units, and perhaps even clans, who have proven themselves in uncountable battles, showing not just great strength and deadly martial prowess, but also steadfast loyalty and a bold and courageous nature. They are formed into a hard-hitting shock unit, a force capable of breaking enemy formations the way a heavy warhammer crushes shale.[4a]
