OK I know I'm not crazy. Somewhere in the core books it talks about if you try to use turbo lasers or big weapons against small ships there is additional difficulty or penalty of some sort. There is a small sentence hidden that says point defense lasers and such if used to target silhouette four or smaller craft, are easier to shoot.
I have read the sentence and for the life of me can't find it. I even put it in my notes of one of my adventures.
I know I'm not nuts. What was this rule and where is it? I can't find it for the life of me. It's not where you'd think it'd be.
