What the Military Taught Me About Executive Leadership

From Military Leadership to Executive Leadership: Insights for Peak Performance

When I transitioned from military service to the corporate world, I anticipated a challenging shift. The two environments seemed worlds apart. One was defined by hierarchy, physical danger, and clear missions. The other was characterised by matrix structures, political complexities, and quarterly targets.

What surprised me was how much the military had already taught me about high-level leadership in business. This was not just about leadership as a concept; it was about leadership as a practice. It involved daily disciplines, mental habits, and non-negotiable standards that distinguish those who perform consistently from those who only excel when conditions are favourable.

After twenty years of coaching senior executives in Fortune 500 and FTSE 100 organisations, I can confirm my initial suspicion: the principles that drive exceptional performance in military settings are the same ones that yield outstanding results in boardrooms. The context may change, but the fundamentals remain constant.

Here’s what the military taught me, and what I see the best business leaders doing, whether they recognise its origins or not.

1. Clarity of Mission is Not Optional

In military operations, ambiguity about the mission is a liability that can cost lives. Significant effort goes into ensuring that everyone involved, from the commanding officer to the most junior soldier, understands not only what they are doing but also why and what success looks like.

This principle, known as commander’s intent, has a direct equivalent in executive leadership. The most consistently high-performing organisations I have encountered share one key characteristic: their senior leaders are obsessively clear about what they aim to achieve and why. This clarity is not merely a mission statement on a wall; it means that every major decision can be tested against a clear and agreed definition of success.

The most common failure I observe in senior leadership teams is not a lack of effort or intelligence. Instead, it stems from the absence of this clarity. Teams work incredibly hard in multiple directions, coordinating activities without ever fully agreeing on what they are working toward.

2. Discipline is What You Do When No One is Watching

Military discipline is often misunderstood in civilian life. It is not merely about following orders without question. It is about maintaining standards of preparation, execution, and behaviour, regardless of external pressures, fatigue, or the temptation to cut corners.

The relevance to executive leadership is direct. Truly exceptional leaders are not those who perform well when everything is going smoothly. They are the ones who uphold their standards of thinking, communication, and decision-making under pressure, when they are tired, and when no one senior is observing them.

Discipline, in this sense, is deeply personal. It involves the preparation you undertake before a difficult conversation, not because someone is checking, but because you know it matters. It is about the rigour you bring to a decision at 17:00 on a Friday when the path of least resistance is to defer. It is about the consistency between how you behave in the boardroom and how you act in the corridor.

This consistency, between public and private standards, is one of the most reliable markers of exceptional leadership I know.

3. Debrief Ruthlessly, Blame No One

One distinctive practice in military culture is the after-action review. This is a structured, honest examination of what happened, what worked, what did not, and what should change. Critically, it is conducted without blame. The goal is learning, not punitive accountability.

This practice transfers directly and powerfully to executive teams, yet it is almost universally absent from them. Most senior leadership teams excel at celebrating successes and are politically adept at managing failures. However, they rarely engage in the honest, structured examination of their own performance that genuine improvement requires.

The leaders and teams that improve the fastest are those who have built a culture of psychological safety and the habit of examining their own performance with the same rigour they apply to their markets, competitors, and direct reports. This process can be uncomfortable, but it is irreplaceable.

4. Calm is a Decision, Not a Temperament

There is a persistent myth that some leaders are naturally calm under pressure while others are not. In my experience, this is largely untrue. What appears as natural composure in exceptional leaders is, upon closer examination, a practised discipline. It is a deliberate choice to regulate their response to high-pressure situations rather than react impulsively.

Military training instils this discipline. You are placed under controlled pressure repeatedly until the physiological and psychological responses that pressure produces become familiar and manageable. The goal is not to eliminate the stress response but to prevent it from overriding your judgment.

The executive equivalent may be less formal but is equally achievable. The leaders I have coached who are most effective under pressure share a common trait: they have developed a conscious relationship with their own stress responses. They recognise their warning signs and employ practices such as breathing techniques, physical preparation, and pre-performance routines. These strategies allow them to bring their best thinking to high-stakes moments rather than their most reactive selves.

Calm under pressure is not a personality trait; it is a skill that can be developed.

5. You Lead People, Not Roles

Military leadership at the unit level is intensely personal. A platoon leader knows their people—not just their capabilities and limitations, but also what motivates them, what frightens them, what they take pride in, and what burdens they carry.

This knowledge is central to the mission. Discretionary effort—the difference between what people do because they must and what they do because they choose to—is the margin between adequate performance and exceptional performance.

In the early 1980s, I had the privilege of leading a multinational Military Police platoon composed of personnel from four nations: the Royal Military Police (United Kingdom), Feldjäger (Germany), Koninklijke Marechaussee (The Netherlands), and the Belgian Military Police.

The British Royal Military Police contingent had recently returned from a deployment in Belfast, where they operated in a highly volatile and demanding environment. This experience had left a profound impact on them. They were constantly alert, highly sensitive to their surroundings, and carried the stress of their operational experiences with them. Even something as simple as a door slamming unexpectedly could trigger an instinctive reaction, causing them to immediately "hit the deck."

As their leader, I quickly realised that my responsibility extended beyond operational effectiveness. My task was to help them transition into a new reality. They needed more than orders; they required a renewed sense of purpose, confidence, and stability. By providing clear direction, meaningful objectives, and a mission that allowed them to succeed, I created the conditions for them to adapt to a different environment and regain trust in their abilities.

That experience taught me an important lesson about leadership: when people have been shaped by challenging circumstances, successful leadership is not about demanding change. It is about helping them navigate uncertainty, rebuild confidence, and embrace a new normal in which they can perform, grow, and thrive.

The equivalent at the senior executive level is understanding that the people in your organisation are not merely resources to be deployed. They are individuals who have made a choice about where to invest their best years and their highest capabilities. The leaders who earn the deepest loyalty and the most sustained high performance are those who take that choice seriously.

This does not mean being soft, permissive, or emotionally indulgent. In the military, the leaders most respected by their people were typically those with the highest standards, not the most lenient. What it means is being genuinely interested in the people you lead as human beings—not as a management technique, but as a fundamental expression of what leadership truly is.

What This Means for You

These five principles are not exotic. Most senior leaders will recognise them and believe, to some degree, that they already apply them. The more useful question is where the gaps lie.

In my experience, most senior leaders excel in mission clarity when things are going well but struggle with it under pressure. Most maintain discipline in visible moments yet let it slip in private ones. Many have a cultural aversion to the kind of honest debrief that genuine improvement requires. Most manage their pressure responses reactively rather than by design. And many lead roles rather than people more often than they would like to admit.

None of these gaps are character flaws. They are the natural consequence of operating in environments that reward output over reflection and performance over development. Closing these gaps is not about trying harder; it is about looking honestly at where you are and making a deliberate choice to operate differently.

That is, in the end, what both military service and executive coaching have in common. They both ask you to hold yourself to a standard that is higher than the one the environment requires of you. And they both show you, unambiguously, what becomes possible when you do.
