This is a cause close to Prince Harry's heart, having served with the British Army for 10 years and undertaking two tours of Afghanistan during that time.

Harry, 39, and Meghan, 42, spoke about the importance of the program's resources and support.

The couple watched on during the ribbon-cutting ceremony outside of the facility.

The Duke and Duchess of Sussex wore poppy pins to commemorate military members who have died during service.

Remembrance Day takes place on November 11, with the British Royal family expected to attend their traditional service.

Harry and Meghan are expected to mark the day closer to their home in Montecito, California, where they live with their children Archie, four, and Lilibet, two.
