Bronzino’s Galloper Guns follow the rules for cannons (the smaller kind). The following exceptions apply:
Small Calibre
The maximum range you can guess is 24". The shots are Strength 7, D3 wounds, no Armour save.
Rapid Movement
The Galloper Gun is harnessed to a warhorse ridden by one of the gunners. This enables the Gun and its entire crew to move 8" (the remaining crew are assumed to jump on the harness and hitch a lift). The Galloper Guns may march move. If the Galloper Gun is charged, the crew may hold or flee. If they flee, the Gun is assumed to be limbered up immediately without any movement penalty. If the Gun and crew are caught, they are destroyed.
Close Combat
The crew fight in hand-to-hand combat as normal. The mounted gunner fights as normal from horseback.
Deployment
The Guns are deployed as separate teams, each Gun and its crew operating as an independent unit. Bronzino must be deployed together with one team, but he can then ride from one team to another or operate on his own as a separate character. When he joins a team, he follows the normal rules for characters joining war machines.
