Thx. I'll try this out when I am back (in a week or so).
From what I remembered from when I was reading about the parameter, wouldn't this change have the side-effect of making the sniper prioritise targets that it can't penetrate reliably? i.e., not the soft targets.
(not that it matters, though, anyway, since snipers are getting baby-sat).
Yes it'll make him more likely to fire on heavy vehicles instead of light ones where his penetration is "wasted". I don't think anyone really cares what the sniper's autoattack priorities are though.
