I have a question regarding the targeter wargear on page 135, which is stated as reducing all penalties on ranged attacks by one step.
Say that, for example, I am firing an autogun using full auto (-10), at a target in fog (-20), who is in combat with an ally (-20) and I'm fatigued (-10). This imposes a cumulative penalty of -60 to my ballistic skill test.
Does the targeter reduce the cumulative penalty of -60, to -50, or does it reduce each individual penalty by 10, meaning that the final penalty is only -20 (-10 for the fog, and -10 for the nearby ally)?
