CAFIB 20 is a "Permanent ID Card" and the CAFIB 13 is a "Temporary ID Card". CAFIB 13 is issued by your local Military Police Ident Section. Your Res F Unit should provide you with an ID Request Form and make an appointment to be processed. The CAFIB 20 will follow in a few months.
Also, I don't believe they use the term "CAFIB" any longer.....I think it has been changed to NDI 20 or 13.
