The difficulty of combat checks when firing from vehicles or starships is based on comparing silhouettes of the firing ship and the targeted ship (even if the target of the attack is not a vehicle or starship), and is outlined here.
|Firing vessel has the same silhouette as target, or the silhouette is one larger or smaller than the target.||Average (Two Difficulty)|
|Firing vessel has a silhouette two or more points smaller than the target vessel||Easy (One Difficulty)|
|Firing vessel has a silhouette two points larger than the target ship.||Hard (Three Difficulty)|
|Firing vessel has a silhouette three points larger than the target ship.||Daunting (Four Difficulty)|
|Firing vessel has a silhouette four or more points larger than target ship.||Formidable (Five Difficulty)|
This reflects the fact that large ships find it difficult to hit small, fast vessels, and their bulk makes them an easy target for those same small craft. Thanks to the advanced targeting computers installed in most starships, the range of a shot has no bearing on the attack’s difficulty; if the target is within range, a starship can hit it. The check is further affected by modifiers brought on by starship maneuvers, talents, terrain, or any other modifiers at the Game Master’s discretion.
When attacking a ship of silhouette 4 or lower, the defender chooses which defense zone the attack hits. Smaller ships are more agile and constantly in motion, meaning that during combat they are constantly juking, dodging, evading, and generally positioning themselves so that their strongest defense zone is always facing their attacker. When attacking ships of silhouette 5 or higher, the defense zone affected by the attack is determined by the position of the ships in combat. The relative position of ships in combat is determined by both the Game Master’s and the Player Character’s actions, and is illustrated through the cinematic game-play style inherent in Edge of the Empire.
