Sergeant Francis Sullivan, RM

I have just purchased the medals of Sgt. Francis Sullivan, RM. They are 1939-45 Star; Atlantic Star; Africa Star, clasp, North Africa 1942-43; War Medal 1939-45; Korea 1950-53 (Ply/X.3644 F. Sullivan Cpl. R.M.); U.N. Korea 1950-54; Naval General Service 1915-62, 1 clasp, Malaya (Ply/X.3644 F. Sullivan. Cpl. R.M.); Naval L.S. & G.C., E.II.R. (Ply/X.3644 F. Sullivan. Sgt. R.M.). I know that he was one of 'The Chosin Few' who served with 41 (Independent) Commando during the Korean War. It is his WWII service on the front end and his Malaya service on the back end that are the mystery. There is a note in the Spink auction listing that states he may have served with the Special Boat Service in Malaya. Any help with Sgt. Sullivan's service details, obituary or date of death if he has passed would help with compiling his story in more detail. Quite an impressive campaign group!
