The Invictus Athlete, The Helicopter, The PTSD Episode And The Beautiful Ending

The 2018 Invictus Games have come to a close in Sydney, but not without some tear-jerking moments.

It was the moment that epitomised what the Invictus Games is all about.

It later became clear that Guest had a PTSD reaction to the chopper.

The beautiful act of sportsmanship was honoured at the Closing Ceremony on Friday night when Vermetten was awarded the Above and Beyond Award.

On their last day in Australia, before they head to New Zealand during the tour, the Duke and Duchess of Sussex took to the stage to close the Games.

With honesty, Meghan Markle opened up to the crowd as she praised the family and friends of the competitors for their support.

"During this year's games in Sydney I have witnessed the most amazing support networks that surrounds competitor," Meghan said.

"The support system on the ground here at Invictus is unlike any other. It's not just cheering on your own but realising that your own becomes everyone in the Invictus family."

After Meghan's speech, the Kingdom Choir, the gospel choir that sang at her wedding with Prince Harry, took to the stage.

Prince Harry brought the Games to a close, and used his speech to praise the competitors for their bravery, and their reminder for everyone of the importance of asking for help when it is needed.

"By simply being here and fighting back from some of the darkest experiences known to anyone, you have become role models for everyone at home or in the stands who might be struggling with their emotions or with a mental illness," he said.
