An interactive video installation will be unveiled in central London today to broadcast stories from a new generation of veterans - encouraging the nation to rethink remembrance.

The four 60-second films by the Royal British Legion, featuring experiences from the younger generation of the Armed Forces community, will be played on seven monoliths in Paternoster Square.

In each film, a story of conflict or injury is narrated by a Second World War veteran aged between 88 and 97, in military dress with some proudly wearing berets and medals.

At the end it is revealed that the stories do not belong to the speaker, but to a younger veteran or member of the Armed Forces aged between 29 and 34.

The films, also available online, have been released to challenge the view that the poppy and remembrance are only associated with the First and Second World Wars and elderly veterans.

Members of the public are being urged to recognise the service and sacrifice made across all generations of the British Armed Forces including the most recent conflicts.

The fundraising target for the Poppy Appeal 2016 is a record £43m, with more than 45 million poppies being distributed by 150,000 dedicated collectors across the country.

Claire Rowcliffe, director of fundraising at the Royal British Legion, said: "Individuals and families from across the generations of our Armed Forces community need the Legion's support, as well as our older veterans.

"When you pin on your poppy, or pause to remember, we're inviting you to rethink Remembrance and who it is you picture when you think of a veteran.

"The Royal British Legion's vital work wouldn't be possible without the public's generous support, and we hope through our campaign this year we will help people understand who they are supporting when they donate.

"Please wear your poppy with pride in recognition of all generations of the British Armed Forces who have served to defend the freedom we enjoy today."

The optical-illusion video installation will feature seven multi-screen columns, the tallest standing at four metres high.

People will be able to explore the films from different perspectives, with the screens uniting to create a single image from one specific viewing point.

Roy Miller, 92, a Second World War Royal Naval veteran from Wallington, London, narrates the experiences of Stewart Harris, 32, who served in the 1st Battalion Welsh for 13 years.

Mr Harris, from Rhyl, Wales, suffered brain damage and was left blind in his right eye and partially deaf after the Mastiff vehicle he was travelling in was hit by an IED in Afghanistan in 2012.

He also has post-traumatic stress disorder (PTSD).

"I was so low, I was shouting at the kids, getting angry at my wife - I begged her to leave me," Mr Miller reads into the camera.

"I felt alone, helpless. I was taught that soldiers don't discuss feelings."

Royal Naval veteran Marsie Taylor, 97, from London, reads the story of Corporal Ben Poku, 34, also from London, who is still serving in the army.

He works as a nurse on the neuro rehabilitation ward at Headley Court.

"They stretchered in a severely burned man. At first I didn't recognise him. Just a few years before, we had been best friends in the playground," Mrs Taylor reads.

"Now, he was an injured soldier and I was his nurse. He told the doctor it would be better if he disappeared, he said he couldn't tell his family what had happened.

"This man had given up his fight. Finally, he agreed to return with me to our village, where he was welcomed home."

Geoffrey Pattinson, 92, a Sergeant with 9th Battalion The Parachute Regiment during the Second World War, shares the experience of Sam Jack, 29, from Stansted, Essex.

Mr Jack, who served for five years in the Army with 33 Engineer Regiment (Explosive Ordnance Disposal), was shot as a result of friendly fire in 2009 while on patrol in Afghanistan.

He suffered eye and brain injuries upon impact.

"I can't remember my injury. One minute my mates were all there, the next I'm in hospital. I couldn't speak, couldn't move," Mr Pattinson reads.

"The doctor said 'this is as good as its going to get'. We showed them."

Royal Naval veteran Jim Radford, 88, from London - thought to be Britain's youngest D-Day veteran - narrates what happened to Anna Pollock, 34, from Catterick in North Yorkshire.

She is a former Medic in the Royal Air Force who completed two tours of Iraq but has been left heavily reliant on a wheelchair following a sudden bleed on her spine.

"I love the feeling of being strong - I'm not weak, I'm a warrior," Mr Radford reads.

"I'll never stop mourning the person I used to be but I'm beginning to like the person I've become."

A survey of 1,000 adults found remembrance, the poppy, and the Royal British Legion's work are most associated with the First and Second World Wars and elderly veterans.

Just over a third of those surveyed identified remembrance with thinking about those who are currently serving.

The video installation will be available for the public to view until October 29, with people able to share their experiences on social media using the hashtag #RethinkRemembrance.
