The Duke of Sussex has been helping to pack and distribute food parcels to military veterans and their families in Los Angeles.
Harry joined the Walker Family Events Foundation, a non-profit organisation for servicemen and women and at-risk communities, last week to offer his support.
The Duke, who served in the forces for a decade, was pictured in a black face mask and casually dressed in a baseball cap, polo shirt and jeans as he helped to sort bags of provisions in Compton, Los Angeles.
Ex-soldier Harry was with the LA-based Service Platoon of the organisation The Mission Continues, which connects military veterans with new tasks in under-resourced communities.
A post on the foundation's Instagram account praised the Duke for being "very humble and kind".
"Today I had the honour of meeting and working alongside Prince Harry, Duke of Sussex," it read.
"He joined us in volunteering at Compton VFW for the Operation Nourish program packing and distributing food to our #Compton neighbours.
"He is very humble and kind."
A spokesman for the Duke of Sussex said: "It was a private day."
The Duke ended his military career in June 2015, after two tours of Afghanistan.
He also founded the Invictus Games in 2014 - the competition for injured, sick and wounded Armed Forces personnel and veterans.
