Understanding the WW1 medal codes

[Asil76]

Hi,  This may have been already discussed on here at some point but I was wondering what the numbers and letter before the service number on WW1 medals mean.  

for example DM2/ then the service number or 6/ then the service number,  I haven't seen many medals with number and letter before the service number, I had some WW1 naval medal once which had lettering on but was after the service number and meant what they were in the navy. is this the same thing?

Sorry for the late reply, there is an online list somewhere which I can't find at the moment, When I get time I'll try to find it and post a link here for you.
