Well, to state the obvious, Royal Marines. Can't read the legend on the reverse. What does it say?

Bayonet Training Medal, I believe.

What you have may be one of the medals issued through the staff of "Physical and Bayonet Training", who operated competition and sports in France during WWI, and the Army School of P & BT. (I'm going off bits and pieces that Google is revealing to me, using phrases like "Physical and Bayonet Training"... )

That lettering on the bottom part of your medal may provide more information.
