With a BCD, he won't get any. I truly hope he does get a BCD, and time in the brig. What a dumba$$. He's a volunteer in the ARMED SERVICES. He's not only a volunteer, but his NEC is designed specifically around WEAPONS DESIGNED TO KILL THE ENEMY before they can kill you.
Now, if he was really an objector, he would have found that out in "A" school, when they talk to you about your rate, etc.
As a Navy vet, I am truly disgusted.
I personally believe that the only people who should ever be able to request "conscientious objector" status, are those who are drafted. If you sign up for military service by your own free will, face the music!
Get him out of the Navy. He's a liability and a security threat!
