It should be a single medal awarded at 5 years followed by a bar for every subsequent 5 years with a rosette worn when the ribbon alone is showing. That should show a maximum of 8 bars, do-able with the standard ribbon length, the rosettes change to gold every 4th one. This should account for the individuals out there that manage to put up with the Armed Forces from the age of 18 to 60. It should replace the QVRSM but not the LS&GC as this is still a matter of enormous pride to some and equally so to some that don't have it. You note that I suggest that reservists as well as full time qualify for the same medal, this is not a slip, remember, the true worth of any medal is only known by the wearer.
