The King is set to lead the UK in a two-minute silence to remember those who died in conflict.
Charles will be joined by members of the royal family and senior politicians who will lay wreaths in London on Sunday at the National Service of Remembrance at the Cenotaph.
About 10,000 veterans will take part in the Royal British Legion’s march past, with over 300 different Armed Forces and civilian organisations represented.
People of all ages will be among those marching – from bereaved children and military cadets, through to some of the last surviving veterans of the Second World War.
Prime Minister Andy Burnham said: “I’m incredibly proud to be honouring those whose sacrifice continues to protect our way of life to this day.
“Remembrance Sunday gives us an opportunity, not only to mark that sacrifice and offer our gratitude, but also to reflect on its significance. To reflect on the selflessness and courage it takes to commit your life to protecting others.
“I want to offer my personal thanks to those who served and those who continue to serve in our Armed Forces communities to this day.”
RAF veteran Steve Hooper, 43, served as a mechanical transport driver during the Iraq War. He will be marching with the Invictus Games Alumni group.
He said: “I saw a lot of trauma in Iraq as an ambulance driver, and when I came back, I was struggling with sleep and having flashbacks. If it wasn’t for the support I received from the Royal British Legion through the Invictus Games, I don’t know where I’d be today.
“I am proud to be marching alongside my fellow team members as we reflect on our recovery journeys and remember all those who weren’t as lucky. I’ll also be thinking about the families who still live with the impact of service and conflict. For me, it’s a time to pause, acknowledge and remember.”
At 103 years old, Women’s Land Army veteran Annie Duplock will be taking part in the march past for the first time.
Ms Duplock joined the Land Army in 1940, aged 16, having lied about her age to enrol.
Based at a farm in Leicestershire for four years, she worked long days milking cows, ploughing fields and harvesting crops, helping to feed the nation during the Second World War.
More than 80 years on, she said: “I feel very honoured to be taking part in the parade and to represent the Land Girls. I’m very excited, although a little apprehensive as I don’t quite know what to expect.
“I think it will be a very emotional day, bringing back memories of all those who didn’t return home. It will be lovely to be there and remember them.”
