In the films and series we have repeated situations where characters shoot at vehicles (like the stormtroopers at the falcon, Leia at slave one, rebels at AT-ST, ...). They do this not only with just heavy weapons but also with blasters.

Now my question here is easy: In the rules do they even have ANY chance of accomplishing anything (aside from the occasional black dice to the pilot)?

From what I can see normal weapons could theoretically get up to 15 or max. 20 damage....which would be lower than the soak of even a TIE fighter or the falcon. And for a critical you need to do damage at least.

Or am I overlooking something?
