Q. Why are there no women guarding Buckingham Palace?
In the British Armed Forces, women are not permitted to serve in combat units (that is cavalry and infantry).
They are however permitted to serve in combat support units, which includes artillery, engineers, air support, logistic support and other branches of the service.
In April 2007, the first women in the British Army served on detachments of the Queen's Guard when the King's Troop, Royal Horse Artillery took over the guard at Windsor Castle.
