Prince Harry's Invictus Games are in full swing in Vancouver and Whistler, Canada, and Team U.S. athletes exclusively tell PEOPLE about what the event means to them.

The Invictus Games are back! Prince Harry and Meghan Markle are in British Columbia, Canada for the first ever winter edition of the international adaptive sport competition, a cause very near and dear to Harry's heart since he founded the Games in 2014.

A video shared by Meghan Markle shows Prince Harry's reaction to a Team Australia 'tradition' continued at Invictus Games.
