This is the shocking moment Scotland and England fans clashed at the UK's largest army base - while bagpipes continued to play in the background.
Footage shows rival supporters chanting at each other from opposite sides of Catterick Garrison in North Yorkshire before things took a violent turn last week.
A group of men were filmed singing Three Lions (Football's Coming Home) towards another group of men who were chanting back from an adjacent building at the barracks.
The group of around ten Scotland supporters, some dressed in kilts and Scotland tops, then try to drown out their rivals with bagpipes.
The piper continuously belts out Scotland the Brave while surrounded by fans wearing Scotland strips and kilts.
The clip then flips to footage taken afterwards which shows the two groups of men involved in a violent brawl.
Around a dozen men, most wearing Scotland strips and kilts, huddle and push each other whilst targeting an England supporter.
The man, covered in an England flag, was filmed cradled on the floor as a male kicked him in the back and the stomach.
The brute then swings and punches him in the face while his victim tries to protect his face with his hand and flag.
A piper continues to play on their bagpipes throughout the whole incident.
The initial footage showing the rival sides trying to drown each other out was shared on social media on Wednesday shortly followed by a video of the brawl.
An British Army spokesperson said: "We are aware of an incident last week in Catterick. We will assist with any enquiry.
"If any soldiers have been found to not be meeting our Values & Standards, appropriate disciplinary action will be taken.
"Service Police are investigating and it would be inappropriate to comment any further at this stage.”
