Earlier this year, Prince Harry and four soldiers went on a freezing cold mission to the top of the world.
The soldiers were badly injured in Afghanistan, and they wanted be the first unsupported group to reach to the North Pole.
The wounded servicemen had a tough time, and Prince Harry said he learnt a great deal from them.
"Myself and my brother, and a huge majority of the British public, support these guys in everything they do.
Prince Harry added: "After doing a very small stint in Afghanistan, I like to think that I've got a rough idea of what goes on out there and how they feel."
