FAQ: How exactly do Chaos Dwarf Blunderbusses work with the Stand & Shoot charge reaction?
(Rule)Description: The rules are applied exactly as with any other unit. If the chargers start within 12" then any models within 12" may be hit. If the chargers are outside 12", the charging unit is stopped at maximum range as normal, and so in this case only the front rank of the charging unit will be in the zone of fire.
