where is this rule?
The rules state that crit icons don't effect fighters. Other than that, all the normal rules for attack dice apply. So why WOULDN'T accuracy results work vs fighters?
It is a VERY common mistake. The rules say crits don't effect fighters, and generics don't have tokens so accuracies don't effect them, so people start thinking "only hit icons effect fighters", when that isn't what the rules actually say.
Exactly this.
You get the same kind of confusion from new players with black anti-squadron dice on ships. Some people assumed they worked out to medium range simply because all the anti-squadron dice up through wave 1 did. This is because they were blue dice (which by default go to medium range), not due to any specified "flak goes out to medium range" rule.
