This is the moment a shocked tourist was pushed out of the way by a member of the Queen's Guard at Windsor Castle.
The woman, who had crossed a rope barrier, screamed in shock as she was shoved from behind by the soldier, who was wearing his ceremonial bearskin hat.
The tourist was not injured and managed to remain on her feet despite the incident which took place at the Queen's official residence.
The Queen’s Guard are charged with protecting official royal residences. They are known for their distinctive uniforms of red tunics and bearskin hats.
The soldiers are picked from one of five infantry regiments and have been protecting royal residences for three centuries.
Tourists like to have their photographs taken with the soldiers who are wearing their ceremonial uniforms.
However, if someone impedes their progress, the soldier will shout 'Make way for the Queen's Guard.'
The Ministry of Defence said: 'The Household Division is proud to guard Her Majesty and honoured that people come from around the world to watch our ceremonial spectacle.
'The ropes are there to protect both the public and our soldiers; please stay behind them.'
It is not known exactly when the incident took place.
This is not the first time this year a Queen's Guard has had to rebuke tourists for careless actions or getting too close.
Another of the distinctive-looking soldiers shouted at an over-eager tourist who got a little too close while moving in for a photo outside the same castle last year.
The hilarious video shows the oblivious visitor attempt to pose for a picture, forcing the guardsman to boom: 'Stay Away!'
Stunned onlookers mutter as the startled man spins on the spot and offers an immediate salute after the order is barked in his ear.
The units, manned by fully-trained, serving soldiers, have more than 350 years of history and have defended monarchs since Charles II took the throne after the English Restoration in 1660.
There are thought to be guidelines in place for guardsmen to deal with nuisances, which begins with stamping their feet and shouting.
Raising a rifle is considered a 'final warning', after which the guardsmen is allowed to detain the person in question.
