[quote]Being colorblind would cause too big of a risk to have you responsible for people's lives and military hardware. It might not affect you 90% of the time, but that 10% could endanger you or others[/quote] This. Granted, there are probably less qualified candidates in your army already, but you already have a known hinderance. It's not in their best interest to put somebody into their armed forces who has a pretty clear hinderance on them.
