The Royal Scots Greys were the first regiment of dragoons raised in Great Britain (1681). There are now half a score of dragoon guard and dragoon regiments, all mounted and equipped as medium heavy cavalry. They are armed with carbine and sabre, and wear metal helmets (except the Scots Greys). This noted regiment has served with distinction in all parts of the world, and has already counted big in the British defense in France and Belgium. The "Grey" does not refer to the uniform, but to the horses, which all have their tails trimmed half-short.
