So this could just be FFG bad wording but I found this interesting.
I noticed in the full Rebel spoilers that were posted on Facebook on the Tactical Scrambler it says when you obstruct an enemy attack the defender rolls 1 additional die. Contrast that with V1 tactical jammer that merely said "Your ship can obstruct enemy attacks" and the base rules specify that any obstructed attack automatically gives an additional defense die. Normally of course ships were not able to obstruct attacks at all.
Tactical Scrambler doesn't say that it enables you to obstruct attacks, it just says "when you do" so I suppose one could argue the wording implies that you can but if ships can't normally obstruct that's very poor wording not to explicitly grant that.
Speculation time: maybe ships CAN naturally obstruct attacks by default now? If so maybe obstructed doesn't automatically grant an extra die but is only observed for procing specific game effects (actual obstacles would specifically grant a bonus die presumably)? If it does give an extra die though (highly unlikely in my estimation) then Scrambler gives a second? Doubt that is what's happening.
Another wrinkle to this though the new Outrider title: "If your attack is obstructed the defender rolls 1 less die". So under V1 rules that's just Dash crew rules turning off the bonus obstruction die. If ships could naturally obstruct without giving a die though that makes Outrider kind of insane. If they can't though then Tactical Scrambler has somewhat nonsensical wording. That just leaves obstruct naturally with ships AND get a die which seems mechanically ridiculous.
I don't know, smart money is probably just on bad wording knowing FFG but the way these particular cards are phrased seems a bit wonky.
