Umm.. the British Military is made up of units from the United Kingdom and a few old British Empire units, such as the Ghurka Rifles.
Now the Black Watch (Royal Highlander Regiment) is a Scottish infantry regiment one of 6 Scottish infantry regiments (the other is a Guards regiment).
Here's a handy link for the land forces of the British Military and the Commonwealth:

for a list as of 1995 here's a link:

I assume this is related to the deployment of the Black Watch to the area south of Baghdad to relieve US forces?
