Britain's Prince Harry has been hailed as an excellent leader of men.
The 30-year-old royal recently walked away from his career with the British military but one of his former colleagues, James Wharton, has hailed his leadership skills.
He recalled: "During that decade he served on the front line in Afghanistan twice, qualified as an Apache pilot, was a forward air controller and even found the time to organise the inaugural Invictus games in London.
"Alongside all of this, he managed to do the core job he was employed to do originally - command men - which he did excellently. I know this because I was one of those men, once."
James said that despite the tough conditions they found themselves in, Prince Harry always helped keep moral high.
Writing for the Huffington Post, he explained: "I spent some weeks sat next to him in a tank in the summer of 2008, on the Prairies of Alberta in Canada.
"During that period, we conducted hard war training, often working in very tough conditions and going days without sleep, but, with the company of our driver, our small crew of three enjoyed many moments of hilarity and morale was, mostly, sky high throughout our training."
