Time for Todd's Tartan Trivia:

The Murray of Atholl tartan is used by a couple of Scottish Regiments:

The Transvaal Scottish of the South African Defence Force (Pipers wear Murray of Tullibardine – the Marquis of Tullibardine is the son of the Duke of Atholl).

The Tartans Authority's on-line article about Regimental Tartans lists these units:

Atholl Highlanders
The Pipe Bands of Trinity College, Glenalmond, Scotland.
4th S.A. Infantry (South African Scottish)
Scottish Horse, Pipers (now part of the Scottish yeomanry, or Territorial Reserves)

The Atholl Highlanders are the only private army in the United Kingdom. The following web site has some nice photos of them "in action" at Blair Castle, the ancient seat of the Murrays:
