Stoll, which was set up during the Great War in 1916, provides housing and support for the nation’s ex-service men and women.
The new memorial was unveiled as its veterans honoured all those who have served in the Armed Forces by observing the two-minute silence at 11am on Friday at its HQ in Fulham Road.
Two days later Stoll members will be in central London on Remembrance Sunday (November 13) where they will be joined by hundreds of other veterans to proudly march past the Cenotaph.
The new video was released to coincide with the special time of the year and Stoll's 100th anniversary, and shows the support it provide for vulnerable veterans.
It features vet Ian Camps, who said: "Stoll provided me with a flat in west London and made sure I had the support I needed at the time to get back on my feet.
"I now have a place I can call home, I have my sail and rudder back and a life to look forward to. I am one of the lucky ones."
Speaking of the parade and Stoll's Centenary, the charity's chief executive Ed Tytherleigh said: "The Cenotaph parade is incredibly important in ensuring we remember those who have served the country and those who have fallen during conflict.
"It gives us the chance to stop and reflect on the huge sacrifice those individuals have made. Today, just as Stoll did 100 years ago, we are proud to provide housing and support to Veterans in the greatest need."
Finally, a gala dinner marking Stoll's centenary and Remembrance Sunday will take place on Monday, hosted by TV star Christopher Biggins.
As part of its centenary celebration Stoll is also holding a series of fundraising events including a Christmas Carol Concert on Thursday December 8 which will be attended by Stoll’s Patron, Her Royal Highness The Countess of Wessex, veterans and local people.
Among other guests attending will be Ben Stoll, the great grandson of the charity's founder, Sir Oswald Stoll. He said: "My great grandfather founded Stoll when he saw the huge challenges that disabled and wounded Veterans faced coming back from World War One.
"The issues that many Veterans experienced 100 years ago - the need for housing and support - are still just as important today and I am delighted that my great grandfather's legacy is being continued 100 years on."
