There seems to be a fair bit of research out there suggesting colour blind people have some advantages as hunters as the increased sensitivity to shape and texture means they are less likely to be fooled by camouflage.
This certainly bears out for me as I always had a knack for spotting animals from a young age and it's now become my career (bugs and fish mostly!).
It'd be interesting to see any stats but i'd be very surprised if colour blindness was a factor in failing to properly identify target incidents.
