Escape from the Mines (Shunna Maza , Ubi Sunt & Callie)

[DM Vitkyng]

It is just the Heavy Weapons proficiency,  hence Sunt is proficient, his one useful skill here.

As per https://swse.fandom.com/wiki/Lambda-Class_Shuttle

the ship has a crew of 6  1 Pilot, 1 Co-Pilot, 2 Gunners, 1 System Operator, and 1 Engineer. [these links also describe what each of these roles can and cannot do. Remember there is a trickle down, one person can act in multiple roles, but then the ship suffers from a lack of action economy.  A pilot or co-pilot can fulfill any other role, but then can't put their all into piloting etc.] 

The weapon complement, and who controls which, are: 
Weapon Systems
2 x Blaster Cannon, Batteries (2 Gunners)  [Fire Arc: Forward]
    Attack Bonus: character BAB+2 (-5 Autofire), Damage: 5d10x2

Blaster Cannon (Copilot) [Fire Arc: Forward]
    Attack Bonus: character BAB+2 (-5 Autofire), Damage: 5d10x2

Laser Cannons, Twin (Pilot) [Fire Arc: Aft]  yup the  one weapon that only the pilot can shoot shoots backward, remember the Pilot can control any of the otherweapons too, it just eats up their actions.
    Attack Bonus: character BAB+2 (-5 Autofire), Damage: 2d10x2
