If a ship receives critical damage and the roll is 31-60 the System that is hit is "Weapons array" pg 319 CRB. The Effect is "Randomly determine one arc containing weapons; condition applies to all gunner actions using weapons in that arc (a turret counts as being in all arcs)"
My problem is how do you handle turret damage?
1. If the turret counts as all arcs and there are weapons in Fore, Port and Starboard, do I roll 1d3 or 1d4 with the 4 being "aft" and affecting only the turret?
2. If you roll for damage and determine the Fore arc of weapons is damaged does that only affect the turret when it shoots to the Fore arc or since the turret counts as "all arcs" is the turret damaged no matter which arc you are shooting into with it?
3. If the latter part of #2 applies and the Fore and Port arcs are both hit once each, "Glitched", is the turret now "Malfunctioning" because it has taken 2 Critical hits, one from the Fore Glitch and one from the port Glitch?
It seems like the easiest answer would be that there are 5 potential arcs on the ship rather than 4 and 1 that counts as all at the same time, at least for critical damage purposes. That way you just roll and get Fore, Aft, Port, Starboard or Turret. That way you could track each of the "5 arcs" separately.
If #3 is true then Turrets are going to take a beating.
