The same charity initiated the 400km hike to raise awareness on both physical and mental struggles after service.
The main aim of the organisation is to help veterans make the transition into civilian life.
According to one of the team members, the Duke of Sussex said: “These men and women know what service is.”
“They’ve seen and overcome adversity and they won’t let obstacles get in their way.”
“They are paragons of inspiration for communities everywhere. We wish them good luck and good weather.”
The six-man team of serving and ex-service personnel (each with mental or physical wounds) will start their journey on October 10th at the Omani Embassy in London.
The expedition was supposed to happen abroad doing The Grenadier Walk of Oman but will now take place in the UK after being postponed twice due to the pandemic.
“I’m taking part in the Walk of Oman because I want to get that buzz of a challenge feeling again,” said Brian O’Neill to Gazette News.
On Monday, the Duke of Sussex and First Lady Jill Biden paired up for a virtual event honouring wounded service members who would have taken part in this year’s Warrior Games, which was slated to be held this week in Orlando, Florida, but was cancelled because of COVID-related concerns.
Addressing the online audience, Prince Harry thanked them for their inspiration.
“To see every single one of you here with the pride on your faces makes me incredibly happy to know how far you guys have come, the dark places that you’ve been to, and where you are now.”
“Thank you for showing us the way.”
