About this plate
MINISTRY OF DEFENCE fleets, Army (ET), Navy (FN), Air Force (EA). One series because Anexo XVIII II.B treats the three contraseñas in a single provision with a single numbering rule; the branch is decodable from the contraseña. Colours and dimensions are NOT in Anexo XVIII for state plates and are not invented here.
About the format
digit width is representative only, Anexo XVIII II.B lists the contraseñas but states no numbering grammar
