Harry, the younger Prince of Wales, has made it his mission to help veterans who have sacrificed in order to serve their countries.
Ever since Harry himself wore the uniform:
He has worked to help the men and women who fought alongside him:
Former President of the United States George W. Bush has traveled a similar path to his British ally, from his own service in the Air National Guard:
To time spent caring for those who have been wounded in service of the United States:
But now, as Prince Harry opens the Invictus Games - his charity paralympics event - in Orlando, the two leaders have come together. Their nations have been allies for decades, and now they are joining forces to help those who have been wounded in battle.
The first Invictus Games, held in London in 2014, were designed to showcase the capabilities of veterans despite their physical injuries. And in 2016, the hope is that they will begin to erase the stigma that comes with invisible injuries like PTSD. Harry explained:
"The Invictus Games in 2014 in London smashed the stigma around physical wounds. What I really hope for Orlando is that we can do the same for Invisible injuries.
I've spoken to everybody who has severe PTSD to minor depression, anxiety — whatever it might be - everybody says the same thing: If you can deal with it soon enough, if you can deal with it quick enough and have the ability and the platform to speak about it openly, then you can fix these problems.
And if you can't fix it, you can at least find coping mechanisms. There's no reason people should be hiding in shame after they've served their country."
The two men held a symposium over the weekend, addressing the issues surrounding invisible wounds and how to encourage veterans to seek the necessary help.
The games began with opening ceremonies - which First Lady Michelle Obama also attended - on Sunday evening, and will continue through Thursday.
Several wounded American veterans are vying for medals in this year's games.
