From what I was told, a copy of your page 2 should do it. I already submitted those documents when I had to update my page 2.I am an enlisted Sailor and I am asking this because they're requiring a marriage certificate, children birth certificates, SS card while I know the reason perhaps is to add them in DEERS and also, for the BAH. Now my dependents are all in DEERS, and I have been collecting BAH 5 years now. I am just curious and was hoping someone with prior experience will help. Thanks!
