Good job - living in the North of Scotland it's nice to see Cock o' the North mentioned.
Just a couple of minor nitpicks...nothing major
Tidworth's in Wiltshire, not Yorkshire!
Also in your final order of battle you have 1st Bn, Queen's Dragoon Guards - as a Cavalry Regiment I don't think they would be classed as a Battalion? You've switched between the Queen's Dragoon Guards and the Royal Dragoon Guards a few times...is that a typo? Also, if you're using the Royal Dragoon Guards are you using a full post Options for Change order of battle?
