The Chaos Dwarfs can use blunderbusses. A unit with blunderbusses mayb move and fire in the same turn. When they shoot they project a 'fire zone' the width of the unit and 12" straight forward. Any model within this is a potential target and is hit on a 4+. The only exceptions are models behind extremely substantial cover such as a hill or a building. Models behind walls or in woods are hit as normal. Hits are resolved at S3 plus 1 per extra rank up to S5. Ranks count if at least 4 wide. A single character in the front rank will not effect the unit's fire.
