Taking part in this year's National Day Parade (NDP) has helped this father and son bond.
Major (NS) Ang Lin Piao, 45, and his son, Delvin, 16, are part of the parade's Majulah Moment segment.
Maj (NS) Ang, a national serviceman with the Republic of Singapore Air Force, will be among a contingent of NSmen who will hand the state flag to a group of full-time national servicemen and students from uniformed groups.
Delvin, a Secondary 4 student in Changkat Changi Secondary School, will be among the group receiving the flag.
He is representing his school's National Cadet Corps (Air).
The Majulah Moment symbolises one generation passing on to the next the responsibility of ensuring the safety and security of our country.
Speaking about the Majulah Moment, Maj (NS) Ang, now a pilot with Singapore Airlines, told The New Paper: "It is significant and symbolic to us, being able to pass the state flag from my generation to my son's.
"It reflects the passing on of responsibility to continue to defend and maintain the peace for Singapore."
The father and son, who have been attending separate training sessions, look forward to attending rehearsals together beginning this Saturday.
At home, Delvin has been polishing up on his marching with advice from his father, who has been showing him the right steps in their living room.
The NDP is a subject close to the heart of the Ang family as Maj (NS) Ang's wife took part in the 2007 NDP with their elder son, who is 18 this year.
They participated in a mass dance segment that year.
The Majulah Moment complements the key highlight of the parade, the Salute to 45 Years of National Service (Salute to NS45).
