Colorblindness doesn't mean that all red and all green look identical. The gray value can still vary, and usually does.
Someone else posted that he can only tell the difference between red and green traffic lights by their position on the top or bottom. I have trouble believing this, since they're clearly distinguishable even in black-and-white movies by their different saturations. If red and green control lights aren't similarly distinguished, they ought to be.
"Just ask the patient" doesn't work well in practice, because it's the parents of a colorblind child who will usually make the decision. In this respect it *is* much like a hypothetical cure for Asperger's--NT parents often want to cure their child's PDD brain, but most adults with Asperger's say they wouldn't take a cure if it were available. If a cure existed and parents used it during childhood, the eventual adult would no longer have the option of choosing. Should parents make that decision, when the most common case is for parents to want something that the eventual adult won't want?
My son is only seven, so a military career has not yet come up as an option, but he's unbelievable at Where's Waldo. It takes him less than thirty seconds, usually more like ten, because the Waldo camouflage just doesn't work on him.
I asked him if he'd be interested in seeing colors as everyone else does. His response was to get out a Where's Waldo book and begin laughing at my difficulty. I'm taking that as a no.
