I don't know all the details for the turret.. so I'll write what I can. Sorry for the delay.
Adolphus lets loose with a spray from the turret.
BAB +4, Dex +1, 1 action dice, -?? for a burst and other modifiers. Rolled 12 on the attack roll, and a 6 on the action dice = 12+6+4+1=23 before any penalties. I think.
Adolphus' impatience in fully utilizing the ambush bursts forth in the midst of the blasts."Fire, Lieutenant!" Moments later, Lt. Kraas manages to fix the slight mechanical difficulties he was having and engages the forward guns.
I'm not certain at all of Kraas' stats.
