I was trying to make Berwer work and stumbled across an interesting question which I think I know the answer to but thought I would put it out there (since it appears no one has asked before).
If one of my droids has Berwer's target locked and already has performed a white calculate action, when Berwer hits the enemy can that droid perform a red calculate? Thereby having two calculates?
Or in shorter form, if I have access to an action with two different difficulties, does it count as the same action or two different actions? (This could also happen if I have a Tactical Officer on a Reaper thereby giving it both White and Red Coordinate actions).
My brain tells me that no this can't work because I am performing the same action twice, but my heart wants it to be possible if just to give Berwer a reason for existing beyond i5!
Berwer Kret and Same Action Paradox
Short Answer: One Calculate action per turn - no double calc ACTIONS.
Long Answer: Berwer Kret is an interesting creature. He's pretty good at getting some action economy for your squad, even at the cost of stress, because of his pilot ability. In particular, accompanied by Probe Droids (for long-range locks) and a bunch of Vultures or Hyenas, you could get a lot of fully modified* shots off in one round (including energy shells!) The cost comes at a risk, though... because your ships can't have already taken the calculate action that turn. They could instead lock or reposition, and hope that Berwer pulls through for them.
Subsequently, Berwer has to hit with his attack, to give everyone that extra calculate action. He's at initiative 5, so he's likely to shoot near the beginning of the round (and almost certainly, at the beginning of your squad). With luck, he'll be able to Tractor Array himself into a better shot, then Ensnare his chosen prey into a killbox, to ensure that his damage goes through... but if you miss his shot, then your squad will be sitting without the badly needed calculate tokens they want, in order to survive & return fire.
Conclusion: Fielding him (and using his ability) is a risk you need to be willing to take... one with pretty good payoffs, but also pretty big drawbacks if you miss. As a result, he doesn't see much play.
* - lock + calculate ain't terrible!
