Mine Host breaks with the protocol of this blog & tells a tale that did not happen to him in person:
In 1954 Mine Host's father was in the Army & tasked with Royal Guard duty in Sydney, for the occassion of the Royal visit.
Each day they would follow exactly the same routine:
At 2am they were marched into position along a parade route. They stood in position from 2am, at attention, lining the route until mid-morning/midday/early afternoon when Her Majesty passed by.
Shortly after the motorcade conveying Her Majesty had passed they were dismissed by an officer & were then on leave until 2am the following day. (use one's own imagination to fill in the details of this daily leave)
The first day nobody knew what to expect, so the troopers were armed with a .303, bayonet and Three rounds each, to handle any "attack that may be launched upon Her Majesty".
It was patently obvious the first day that by far the greatest risk Her Majesty faced was being swamped by enthusiastic loyal crowds.
Thus the second & subsequent days the .303 and bayonet remained in the armoury. Instead, dressed in full webbing only, each trooper gripped the belt of the trooper to either side, forming what was (hopefully) an unbreakable khaki chain, in an attempt to keep the adoring crowd from crushing Her Majesty & party.
