Leading through uncertainty is one of the greatest challenges any leader will face. Whether you’re navigating sudden market shifts, disruptive technology, or unexpected crises, the path forward often feels unclear. The Marine Corps offers powerful lessons for business leaders: focus on the mission, adapt your tactics, and keep moving even when clarity is scarce. These timeless principles show us how to thrive in volatile, uncertain, complex, and ambiguous (VUCA) environments — the same conditions many organizations face today.

The Fog of War and Leading Through Uncertainty

In the Marine Corps, uncertainty is described as the fog of war. In business, it looks like supply chain breakdowns, new competitors, or sudden regulatory shifts. The real test of leadership isn’t avoiding uncertainty — it’s deciding how to act within it. Harvard strategist Michael Porter once noted that winning organizations don’t just react to change; they shape the environment in which they compete. Similarly, Marines don’t wait for perfect clarity; they move forward, influencing outcomes instead of being controlled by them.

Expect Uncertainty — and Act Anyway

Marines are trained to expect uncertainty as the norm. They understand that waiting for perfect conditions is a luxury leaders rarely have. Instead, they act on the best information available, adapt when necessary, and keep momentum alive. In business, this means replacing the mindset of “We’ll decide when we know more” with “We’ll move forward with what we know now.” Leaders who embrace uncertainty create resilient cultures that continue advancing even when the path is unclear.

Make the Best Plan Possible, Then Adapt Fast

General Colin Powell’s 70% rule is a cornerstone of decision-making under uncertainty: act when you have between 40% and 70% of the information you need. Less, and you’re guessing; more, and you’ve waited too long. Companies like EōS Fitness exemplified this during the pandemic, pressing forward with expansion when rivals hesitated. The result? Rapid growth and market leadership. The lesson is clear: speed and adaptability often matter more than waiting for certainty that never arrives.

Adapt with Purpose, Not Panic

In the Marines, the mission stays constant, but tactics shift as conditions evolve. Businesses that adopt this mindset thrive by empowering teams to adapt quickly without losing sight of the goal. Starbucks, for example, allows frontline employees to make customer-focused decisions in real time — strengthening loyalty while staying true to its mission of inspiring and nurturing the human spirit. Leaders who embrace agility, share information openly, and empower teams to act position their organizations to succeed in any environment.

Conclusion: The Leader’s Choice in Uncertainty

Standing still when conditions are uncertain may feel safe, but it cedes control to circumstances. Moving forward — even imperfectly — gives leaders the chance to learn, adapt, and seize opportunities before competitors. Like the Marine in Rifleman Dodd, you may not know every step of the journey, but if you keep advancing, adapt your tactics, and stay focused on the mission, you will reach your objective. Leading through uncertainty isn’t about having all the answers — it’s about moving forward with clarity of purpose and the courage to adapt.
