Hello! I know that from 2006 all scots regiments were amalgated in tothe Royal regiment of Scotland, wearing the same tartan and a blue Glengarry with dice and this badge:
ButI have seen this picture...the soldier at the back wear a kilt with the cameron tartan, and so a glengarry without dice (as cameron did)
And in this picture the first wear the actual glengarry...but I can see the Royal Highlanders regiment glengarry (blue without dice), the Scots highlanders fusilier glengarry ...and even a glengarry with the scarlet and white dice (argyl and sutherland highlanders)
Do you know the reason?
