On Saturday there's a sporting clash of epic proportion and historical significance. Yet it's one which will garner few column inches in the national press.
First played out in 1907 the fixture has twice been put on hold; as the guns pounded the battlefields and trenches of a Europe torn asunder by the First World War and then again during the Second World War.
Hence why it has taken 109 years for the annual Army v Navy Rugby match to be able to celebrate its actual centenary.
But while the general public may know little about the match, the 80,000-plus tickets up for grabs at Twickenham sold like hot cakes.
That's because for the British Armed Forces it's the highlight of the sporting calendar, an opportunity to celebrate everything that's great about the military and a time to remember those who have served, fought and died over the last 100 years.
Prince Harry will be in attendance, as Patron of the Invictus Games Foundation, which is the official charity of the day for this year’s match.
The Prince will be joined on the day by competitors from the 2014 and 2016 Invictus Games, as well as some of those hoping to be selected for the third Invictus Games in Toronto.
You can watch live coverage of the Army v Royal Navy clash live on Forces TV (Sky channel 264, Virgin 277 and Freesat 165) on Saturday from 14:50 BST, and full coverage of the day itself on Forces.net and Forces News and BFBS Radio Facebook pages.
