Thanks DAB!
In very short terms... the grey cons in GW are there to require you to identify your target.
This ties-in with the F1 help screen and the pull-down flag recognition info found on your F3 screen... and the increased power factor of the optics. (In real life you can see better than SH3 allows you too, so we compensated for it by slightly increasing the power of the optics.)
Sink them all!!!
