Vietnam veteran Martin Zeugofsge's family clapped and cheered as he passed by their vantage point during Adelaide's Anzac Day march on Wednesday morning.
He beamed as his granddaughter, Claire Armstrong, rushed onto the street to give him a hug and kiss.
The pair share a special connection through their involvement with the Australian Defence Force.
More than 40 years after the end of the Vietnam War, 19-year-old Ms Armstrong last year completed the Army gap year and this year enrolled in the army reserve program.
She's now an inactive reserve to focus on studies in international relations and law, but said she had always known she wanted to follow in her grandfather's footsteps.
"We'd always come to the marches and we'd always see him and how amazing it is and how proud he is of fighting for his country," she said.
"He used to come to our school for our Remembrance Day ceremonies and do the odes.
"It was the best feeling when he came to my march out at Kapooka."
Mr Zeugofsge was one of about 6000 veterans, serving personnel and descendants who took part in the annual march.
Another was 97-year-old Sandy Hill, who served in New Guinea during World War II from 1942-44.
Of his service unit of 400, only two - he and Stanley Barrett - participated on Wednesday.
Mr Hill, of Goolwa, has marched every year since he returned from the war, and this year was pushed in a wheelchair by his grandson, Tom.
Streets were closed and spectators of all ages lined the streets to acknowledge the veterans, serving personnel and descendants - many of whom were wearing medals or holding flags.
Marchers were split into 20 groups depending on where and when they, or a relative, served.
The march started from the South Australian War Memorial at 9.30am, and took the procession right onto King William Rd.
