After re-reading the Player Core, I noticed that Operatives should be considered Expert in Simple and Martial guns, and Trained in Advanced - but the Demiplane sheet only has Martial Attack and Advanced Attack, with the Operative sheet showing Trained in Martial and Untrained in Advanced! So for example, the Shirren-Eye Rifle should be 1 higher attack modifier than it shows on the sheet.
I just double checked and at least on my end I’m showing that the Operative is Trained in Advanced Ranged Weapons.
