Yes, I do have severe deuteranomaly. Diagnosed when I was 6 years old.

I've read quite a lot about this, there are many cases where red/green blind people have exhibited above average night vision.

I was also very good at spotting camouflage, since the patterns were designed to fool people with normal colour vision. The only time my colour blindness was a disadvantage was in a contest between regiments, I had to direct artillery fire as fast as possible and the targets were big red boxes in front of the treeline.

Our lieutenant lost his shit when he realized that he had a colour blind forward observer. We still won the contest, my squad handled the measurements impeccably and I verified them on the map. There was discussion of transfering me to other duties after this, but when I asked "Sir, how many big red box targets are there are in real war?" they quickly dropped the issue.

Mmm yes I solved that problem by being a mortar guy in headquarters company. They had access to far better scouts than me.
