Battlestar Galactica: meaning of a Quorum card that destroys ships
The card is Authorization of Brutal Force. The exact text is:


  Destroy 3 raiders, 1 heavy raider, or 1 centurion.


The person playing the card can choose one of the three options.

I don't think you'll find any official rule that will answer the question. It really comes down to standard English grammar. Option #1 is the proper way to parse that sentence. If option #2 is what was intended, it would have to be written the way you wrote it, i.e. with the "and".
