I did a lot of reading on color blindness last night. I have since I was first diagnosed but never in this context until yesterday.
Turns out that color blind people can be better hunters because we look more for shape than color which helps us defeat camo and natural cover...likely how the genetic trait survived all these years.
It also turns out that during WWII it was pretty much unheard of to have arial photo's viewed/analysed without a color blind person on the team also examining the photos...for pretty much the same reason...we just pick up different things.
The nightvision thing is a bit more sketchy. The idea is that with with one part of the retina weakened, the other parts step up (like a blind person hearing better)...not sure how true that is though.
Makes me wonder. I hope it makes me some kind of tracking savant though I know that's highly unlikely

I've never used NVGs but I may get the chance soon. I've been told they're not very good for mantracking and are only really useful for military use where you can't use flashlights to pick up sign. For my use I can have as many lights as I want so NVG isn't really practical...especially if I'm using a pair and somebody flashes me with their flashlight...I've heard that's not fun.
