I have just looked at the "Next of Kin" forms and it states that the service number is mandatory, along with rank held, date of discharge and a whole lot of other stuff my mother doesn't know about her father. So Kyt, are you speaking from experience....because I have not sent in this form because I felt they would take one look at my lack of information and dismiss it. I would be excited to know that this has been shown not to be the case.
