R. M. L. I. - Royal Marine Light Infantry

P. O. - Petty Officer

L/Stoker - Leading Stoker

A/E.R.A. 4 Class - Acting Engine Room Artificer 4th Class

LCDR - possibly Lieutenant Commander?

C.P.O. - Chief Petty Officer

S.B.A. - not sure

E.R.A. - Engine Room Artificer

C.E.R.A.- Chief Engine Room Artificer
