This Saturday one of the biggest sporting events in the forces calendar will take place at the home of rugby. 
The Army/Navy rugby match will be attended by more than 80,000 fans at a sold out Twickenham stadium.
Spectators will also see a new memorial which has been unveiled at Twickenham Stadium to remember England’s rugby players who gave their lives for their country.
The 'Rose and Poppy' Gates are located at the entrance to the West Stand.
There will be a minute's applause 23 minutes into the game, in memory of a fallen soldier - Captain David Seath who died running last weekend's London Marathon. 
The game will also be streamed live via the Forces TV YouTube channel for the first time - giving anyone in the world with internet access the chance to share in one of the greatest sporting events in the British Armed Forces calendar.
