A spokesman for Archewell said former Army officer Harry and the duchess have “committed themselves to remembering, reflecting and honouring service members, veterans, and military families from around the world”.
The couple attended the Intrepid Museum’s gala, honouring serving members and their families before going to the Joint Base McGuire’s-Dix-Lakehurst, which is the Department of Defence’s only tri-service base.
Over 46,000 members of the armed forces and their families live and on the base.
The duke and duchess hosted a luncheon with service members from all six branches of the military.
A spokesman for Archewell said: “Throughout their visit, they discuss mental health, the value of community and living a life of service.”
