One of the several categories of aides de camp to the Monarch in the United Kingdom is styled Aide de Camp General.
These are honorary appointments for senior British Army generals, first made in 1910. There were originally four, but the number was reduced to three in 1988. There were also two in the British Indian Army 1912-1947.
The current practice is for appointments to be made from the Chief of the General Staff, Commander-in-Chief Land Forces and similar levels.
The Aides de Camp General are occasionally required to be present on major State occasions, but otherwise have no military or advisory function.
