When rolling Vision to spot someone, what sort of penalty do you apply to spot them based on their posture? Ranged Target penalty seems too small - a crouched man is as easy to spot as a prone one (-2).

Even more so, Tactical Shooting 27 says that a prone man gives -4 to spot him. That number is equal to the melee attack penalty made from such posture (-4 to strike with melee from prone position), but Tactical Shooting does not outright say what this penalty truly is.

So, in the end, are there true canon penalties for spotting someone in a posture other than standing?
