Former commando Allan Miles never met his World War I veteran father who died months before his birth.
But the OAM recipient believes anyone who has signed up to the Australian Defence Force is linked to previous generations.
“They have a connection to everyone who has served before,” he told AAP.
“We go back to the young men who served in Korea and then in Malaya, they became our instructors for men like myself who served in the 60s and 70s, which was the main conflict period for Vietnam.
“You can’t not be aware of the service of those men and women … just amazing people.”
Australia will pause at 11am on Tuesday to mark the 107th anniversary of the armistice that ended fighting in World War I.
Remembrance Day is used to honour the people who have died in wars since.
The year 2025 also marks 80 years since the end of the World War II in 1945.
Ceremonies will be held at memorials throughout the country.
Mr Miles, who is the chairman of Operation Pilgrimage, an organisation of former commandos, urged younger generations to try to understand the significance of the service and sacrifice being commemorated.
Prime Minister Anthony Albanese will attend the national service at the Australian War Memorial in Canberra to pay tribute.
“We remember every young Australian denied the chance to grow old, and every Australian who came home but never fully left the battle,” he said in a statement.
“We remember every future lost and every future changed forever.
“That is the heart of the pledge we hand from one generation to the next.”
Opposition Leader Sussan Ley and opposition veterans’ affairs spokesman Darren Chester will also attend the national service at the war memorial.
In a joint statement, they encouraged Australians to visit local services or pause in silence to honour those who made the ultimate sacrifice.
“It’s a small gesture, but a deeply meaningful one,” they said.
“In that moment, we are united as a nation in gratitude and respect.
“We will remember them.”
