Some rules on how easy it is to spot people and make ranged attacks. This is all really tricky, since I haven't been able to find any decent data anywhere.
A person is assumed to have good vision out to Perception x 100m. If they try to make a ranged attack against someone beyond that distance, then the effective distance is doubled. This can be offset by either aiming, or using scopes. The biggest advantage of scopes is the perception bonus gained.
| Scope | Atk | Per | Range |
|---|---|---|---|
| None | +0 | +0 | 300m |
| x2 | +5 | +2 | 500m |
| x4 | +10 | +4 | 700m |
| x8 | +15 | +6 | 900m |
Is this sensible? Possibly it should be a multiplier to the perception range, which would make more sense, but give silly results at very high perceptions.
It is assumed that the difficulty to spot someone in an open field is 0.
| Distance | Modifier |
|---|---|
| Up to 50m | +0 |
| 50m+ | +5 |
| 100m+ | +10 |
| 200m+ | +20 |
| 400m+ | +30 |
| 800m+ | +40 |
| 1600m+ | +50 |
| 3200m+ | +60 |
Remember that when trying to spot someone beyond Perception range (P * 100m), then the difficulty is doubled. This makes raw Perception important, whilst still allowing the Awareness skill be useful for spotting hidden things at short range.
If someone is trying to hide, then the base difficulty is their Per * Stealth as long as there is some cover. If cover is poor, then halve the stealth roll.
| Type of cover | Modifier |
|---|---|
| None, flat floor | x0 |
| Grass field | x0.5 |
| Field, bushes or crops | x1 |
| Good cover (50%) | +10 |
| Excellent cover (90%) | +20 |
In rough field, it is assumed that you are not actually hiding being a bush or tree, but there are plenty of other distractions which make it harder to notice you. You may also have partial cover which isn't as good as 50%.
If the target is moving, then the spot difficulty is halved.
