It's important during briefing scenes with superiors of the PCs that you don't give them too much information and end up making the mission too easy. Keep details vague and give them just enough to get them out in the field and into danger. Any actual intel they should have to work for, rather than being presented with it on a plate.
But try not to make the superiors look incompetent, or the players might start to wonder how they got the job...
Mon Mothma: So like, here's our super super nice Admiral Ackbar, to fill you in on all the, like, technical, like, stuff.
Mon Mothma: Because we totally know more than just the name.
Admiral Ackbar: We snared this hologram of the Peace Moon. This field may be a communication zone, a detection perimeter, or just some kind of ruse.
Leia: So we don't even know what it is?
Mon Mothma: Well, it's yellow.
Han: Sounds like we need a plan!
Chewbacca: Yes. Yes it does. Shall we let the Admiral speak?
Admiral Ackbar: There's a tangle of squiggly lines inside, but we don't know what they are.
Mon Mothma: They're also yellow.
Admiral Ackbar: Those were all the technical details our agent snagged.
Leia: I'm sure glad Wedge didn't die for this.
Wedge: Hey, thanks, Princess!
