A veteran gunner of the Royal Marine Artillery (RMA). He wears a single clasp East and West Africa Medal and the China Medal awarded for service during the Boxer Rebellion. He has a single good conduct stripe on the cuff of his tunic's sleeve with the crossed rifles and star of a 1st Class Good Shooting badge above it. A special thank you to John Young for providing information correctly identifying this subject.
I have found a medal sale reference for an East and West Africa Medal with "Witu" clasp being issued to a member of the RMA. The unnamed recipient of the medal mentioned in the 1904 sales sheet was a member of the HMS Brisk's complement. The Brisk also saw service during the Boxer Rebellion, so it is one possibility that this RMA gunner may have been a member of the Brisk's marine complement.
