When we hear the term Total Defence, many of us instinctively think of soldiers, uniforms and the defence of Singapore’s borders. Yet, as the years go by and life takes us beyond the parade square, the meaning of Total Defence has evolved. For many NSmen, it is no longer just about military readiness. It is about resilience in everyday life, unity within our communities and the responsibility we carry as citizens, fathers, colleagues and friends.

Since its launch in 1984, Total Defence has remained a cornerstone of Singapore’s security. Introduced by the Ministry of Defence (Singapore), the concept reminds Singaporeans that defending the nation goes beyond the armed forces. Today, its pillars include Military, Civil, Economic, Social, Psychological and Digital Defence — reflecting the complexities of modern threats. But beyond frameworks and policies, what does it truly mean to those who have served?

For many NSmen, the journey begins with National Service and becomes a lifelong commitment after ORD. During training cycles, NSmen often speak about readiness in terms of physical fitness and operational capability. However, outside camp, readiness takes on different forms — being financially prepared, staying informed and supporting the community during crises.

For example, during the COVID-19 pandemic, many NSmen stepped up in their own ways. Some volunteered in community outreach, others helped vulnerable neighbours, while many ensured business continuity in their workplaces. These actions, though not in uniform, embodied the spirit of Total Defence. They showed that resilience is not only forged in training grounds but also in daily life.

As Singapore continues to navigate an increasingly complex world, the role of NSmen remains vital. Their contributions extend far beyond reservist training. They shape the nation through their families, workplaces and communities.

Ultimately, Total Defence is not a one-day observance or a slogan. It is a mindset. It is the belief that every Singaporean has a role to play in safeguarding the country’s future. For today’s NSmen, it means standing ready, not only in uniform, but in everyday life. Because the strength of Singapore does not lie solely in its defences, but in the collective will of its people to protect, support and uplift one another.

Here, three NSmen share their thoughts and views on Total Defence with us.

“When we think of Total Defence, most people immediately picture the Military and Civil Defence protecting Singapore. However, it is much more than that. Total Defence is a collective responsibility shared by all citizens, permanent residents, and even foreigners living in Singapore. As a small nation with limited natural resources, Singapore relies heavily on the unity, resilience, and readiness of its people. Total Defence Day, observed on 15 February this year, reminds each of us that we have a role to play in safeguarding our way of life and to be grateful for the stability and opportunities we enjoy today.

Total Defence is built on six key pillars: Military, Civil, Economic, Social, Digital, and Psychological Defence. In times of crisis, these pillars ensure that we, as a nation, can work together to overcome challenges, support one another, and emerge stronger.

National Service plays a crucial role in fostering resilience among Singaporeans. While many view NS training as tiring and demanding, it is instrumental in building mental fortitude and the ability to operate under stress. It teaches servicemen and women to adapt to unusual situations, overcome adversity, and respond effectively in crises — lessons that proved invaluable during challenges such as the COVID-19 pandemic.

Total Defence also prepares us with the right mindset for readiness, even when threats are not immediately visible. It equips us with the knowledge and skills needed to navigate disruptions and helps communities stay vigilant and committed. As John E. Lewis once said, “If not us, then who? If not now, then when?” — a sentiment that captures the spirit of Total Defence and the collective responsibility we all share.”

“Many of us tend to forget that Total Defence Day falls on 15 February as it isn’t the kind of occasion people eagerly anticipate or celebrate like Chinese New Year, Valentine’s Day or Ramadan, all of which coincided in February this year. I’ll admit that I only realised it was Total Defence Day when my army mate dropped a message in our group chat wishing us a happy Total Defence Day. It got a few laughs, yes, but it also made me pause and reflect on why this day still matters.

Looking back on my time serving National Service nearly nine years ago, I don’t think I fully understood why I had to commit almost two years of my life to it. Like many young men, I saw it more as an obligation than a calling. But what I gained from those two years — and in the years that followed through my regular reservist cycles — slowly changed the way I viewed National Service, and in turn, the purpose behind Total Defence.

The lessons went far beyond drills and physical training. They were about resilience, teamwork, responsibility and the understanding that Singapore’s survival has never been guaranteed. These experiences helped me realise that defence is not just the job of soldiers, but a collective effort that includes every citizen in times of crisis.

In today’s increasingly uncertain world, the importance of staying prepared has never been clearer. Singapore must continue to remain strong and adaptable. By showing the world that, despite our size, we are constantly strengthening ourselves — whether in military capabilities, international partnerships or digital resilience — we build not only deterrence, but also confidence and unity from within.

Perhaps it is simply part of growing older, but I now find myself thinking more about the future. I want to see a Singapore where the next generation can live with the same sense of safety and stability that we often take for granted today. That desire makes me appreciate the sacrifices made by those before us, and the responsibilities we continue to shoulder.

So let’s not be too quick to dismiss National Service or Total Defence Day. It is perfectly fair to question their relevance — in fact, that reflection is necessary. But when you start to wonder why they matter, take a moment to look around you. At the peace we enjoy, the opportunities we have and the stability we live with. In that moment, I believe the answer will become clear.”

“Total Defence is a personal responsibility for every Singaporean to contribute to the nation and safeguard our country’s security, so as to prevent enemies or terrorists from attacking Singapore.

It is also the duty of men to serve National Service, where we are trained and prepared as soldiers regardless of our background, whether we are Singapore citizens or Singapore PRs.

National Service has helped me become more physically and mentally prepared to handle different situations, both in Singapore and in everyday life. The soldiering fundamentals I learnt during BMT, Specialist Cadet School, the Signal Institute, and in the battalion through various exercises have shaped my resilience and discipline.

Through National Service, I have transformed from someone who was not very fit into someone who is physically stronger and mentally ready to face challenges. The values and skills I gained from the army will continue to guide and prepare me for the future.”
