At range 2. Can fire using DH-17 blaster pistols AND laser cannon? OR must select only one weapon?

Thanks

Just 1. Because it’s only 1 mini and doesn’t have Arsenal.

Each miniature in the unit must choose a single ranged weapon to shoot each time you attack. The FD is a single miniature, and as such can only shoot a single weapon each time it attacks. The pistols are your 360 degree option for when an enemy unit gets behind them and you can't or don't want to pivot.
