Well, IR/thermal imaging I would at least contend is
an important feature in trying to model a modern battlefield
(especially with regard to tank gunnery). And the experience
of using a weapon mounted Image intensifier is completely
different from using goggles, so there's no "redundancy"
there. Oh dear, I hope I'm not going to have the same
frustrating experience trying to make a Starlight 'scope addon
again!
