Ion Damage and scale question

By Master Su'hil, in Star Wars: Edge of the Empire RPG

I've done a lot of searching on this forum (and AoR and FaD) and haven't found a direct answer to my question. I know what I believe is right, but I wanted to get other people's take (or an official ruling) if possible.

What I know to be true:

All vehicle scale weapons deal 10x damage on personal scale. Vehicle HT is 10x personal scale WT. Armor is 10x personal scale soak. However, it does not state that SS is 10x of personal scale Strain.

Situation:

A vehicle with 3 armor and 12 SS is hit with 5 Ion damage from a vehicle scale Ion cannon.

Question:

Is the vehicle

  • a) reduced to 10 SS after taking 2 Ion damage?
  • b) Disabled, with -8 SS after taking 20 Ion damage?

A

While they didn't call it out system strain is vehicle scale too. Otherwise ion weapons are just too powerful.

FFG is supposed to be a little more relaxed system of rules compared to other systems, best if you not read too deeply into situations like this.
