the Home Guard provided the King's Guard, in recognition of the first anniversary of its foundation. This was repeated in May 1943. Royal Marines units have formed the guard on three occasions. 41 Commando formed the guard in November 1978, while 42 Commando formed the guard in July 1986 and June 2014. In November 2017, the Royal Navy mounted the guard with a company-sized detachment formed of volunteers from 45 ships and shore establishments for two weeks.
