It's not just the Scottish regiments, it's the English too being decimated. When I joined up there were 16 Armoured regiments, three of which were Lancers, 9th/12th, 16th/5th and mine, the 17th/21st. The 16/5 and 17/21 were ammalgamated back in the 90's to form the Queens Royal Lancers, now the QRL is to be ammalgamated with the 9/12 to form the Royal Lancers. The last Lancer regiment in the British Army. It's the same story for the rest of the cavalry and the Royal Tank Regiments.
