There is scaling, personal scale and planetary scale. Most vehicle and starship weapons work in planetary scale, using the silhouette comparison (EotE, pg. 235) to hit (humans are silhouette 1) and dealing planetary scale damage (each point of damage in planetary scale deals 10 damage in personal scale). Personal weapons hitting starships and vehicles isn’t really covered, but I would surmise that the 1:10 ratio would count in the other direction (i.e. 10 damage in personal scale : 1 damage planetary scale). Ranges work as described on EotE, pg. 239. There’s also the Massive attribute that makes critical hits more damaging.
