What advice would you share for someone who has desire to serve, but only qualifies for a handful of Navy jobs due to colorblindness?

I just joined the site, and let me begin by thanking everyone here for your service. It was my onor to serve after, along side, or before you all.

That being said, I now have a 29 year old son who wants to follow in his father's steps and join the Navy. Needless to say, I couldn't be more proud.

He was an honor roll student all through HS, and scored a 90 on his ASVAB. Sounds great, right? Then the realization that a moderate case of colorblindness has all but stripped him of his ability, and in truth, his desire to serve, as it has relegated him to qualifying for a hand full of Navy jobs. No offense to anyone here, but I will not allow him to sign up fto be something that he doesn't want to be, and is honestly, beneath his intelligence. I am so disillusioned, and disheartened right now. Would anyone be able to share any advice? Thanks in advance.
