In Special Forces (and frankly, across the military), you don’t survive without one philosophy drilled into your head from day one: Next Man Up.
It isn’t a slogan. It isn’t a motivational poster in the team room. It’s a way of life. When one man goes down, someone else steps up. When a leader is unavailable, someone else takes the reins. When a task needs to get done, you don’t sit back waiting for permission. You execute.
That mindset is what keeps small units alive in combat, what sustains morale in miserable environments, and what makes the military a master class in engagement and buy-in.
Every soldier, sailor, airman, and Marine learns early that you are not just responsible for your lane; you are responsible for the success of the operation and the people to your left and right.
In transition, though, I see too many veterans forget this. They step into corporate environments expecting someone else to hand them a certification (yeah, I went there…), a playbook, a job description, or a clean, orderly chain of command.
Here’s the truth: the best organizations (the ones worth being part of) thrive when their people live the same philosophy we did in uniform. Next Man Up isn’t just for warfighters. It’s a philosophy that can transform businesses, cultures, and careers.
At its core, Next Man Up is about redundancy in leadership and ownership in execution.
It’s not just covering down. It’s not just about being a backup. It’s about assuming responsibility without hesitation when the operation demands it.
It’s not rank-dependent. A private can step into leadership in the middle of chaos just as a general can delegate down. The operation doesn’t care about your title; it cares about your capability.
It’s about shared trust. Everyone in the unit knows someone has their back. No one is left behind, no task goes undone.
Think of it like this: in the civilian world, people love to talk about “succession planning.” In the military, succession planning isn’t a binder on a shelf; it’s a living practice embedded in every drill, every field exercise, every combat operation.
When your platoon sergeant goes down, you don’t call HR and schedule a hiring board. Someone steps up, assumes the role, and the unit keeps moving. That’s Next Man Up.
You don’t get Next Man Up from a PowerPoint presentation. It’s trained, tested, and lived through repetition.
Cross-Training: Everyone is expected to know not just their job (MOS), but at least a baseline of the guy next to them. A radio operator can run a machine gun. A medic can call for fire. A team sergeant can man the mortar. Why? Because when (not if) someone goes down, the operation can’t/won’t pause.
Leaders Training Their Replacements: From day one, you’re taught to “train your replacement.” It’s not about protecting your turf or hoarding knowledge. It’s about ensuring the operation survives you. You’re expected to pass your skills down to the junior guy, and up to your leader, so the team is always stronger than the sum of its parts.
After Action Reviews (AARs): Every operation ends with brutally honest feedback. Not to blame, but to teach. Why? Because the next time the same scenario plays out, the next man up might be someone who wasn’t in charge last time, but now has the insight to act with clarity.
Drills Under Stress: We deliberately create failure points. Leaders get pulled out of the exercise. Radios “go down.” Casualties are simulated. Why? Because we’re teaching adaptability. We’re teaching every man that the operation will demand leadership from him at some point.
The military doesn’t just hope people are ready for the next role. It forces them into it until they prove they can deliver.
When everyone knows they could be the one called to step up, it changes how they show up every day.
Higher Engagement: People don’t sit back waiting for someone else. They stay switched on, engaged, and ready.
Deeper Buy-In: Soldiers don’t just care about their task. They care about the team’s outcome because they know at any moment it could fall on them to lead.
Greater Respect Across Ranks: When a leader sees a private step up and deliver in a crisis, respect grows. When a private sees a leader who trusts him to take charge, buy-in deepens.
This is the opposite of corporate disengagement. In Gallup’s State of the American Workplace report, only about a third of employees say they’re engaged at work. Why? Because they don’t feel ownership. They don’t believe their presence matters. They don’t think they’ll ever be the one trusted to lead.
The military flips that on its head. Everyone knows their presence matters. Everyone knows the operation literally cannot succeed without them. That’s Next Man Up.
So how does this play out in the workplace? Here’s how veterans (and smart corporate leaders) can take this philosophy and inject it into business:
Cross-Train Teams: Stop building silos. Have your marketing guy learn enough about sales to close a deal. Have your project manager learn enough about operations to run a line. The goal isn’t to make everyone an expert at everything; it’s to build resilience when someone is out or the situation shifts.
Encourage Leaders to Build Replacements: Too many managers hoard knowledge, terrified that if they share too much, they’ll become irrelevant. Flip it. The best leaders are measured by how many people can step into their role seamlessly. Promotion isn’t a threat; it’s a responsibility to multiply capability.
Run AARs After Projects: Instead of endless “status meetings,” run brutally honest after-action reviews. What went wrong, what went right, what needs to change? And (critically) make sure insights are shared across levels so anyone can step up the next time.
Stress Testing and Simulations: Don’t just plan for sunny days. Pull people out mid-project and see how the team adapts. Ask someone unexpected to run the meeting. Drop the “leader” out of the room and let the team work it. You’ll quickly see where buy-in is lacking and where hidden leaders are waiting to be discovered.
Cultural Shift: Everyone Is Responsible: Move from “That’s not my job” to “I own the operation.” That requires leaders who empower, but it also requires employees who embrace the mindset that their contribution could be decisive.
Let’s be blunt: most corporate environments fail because they have no Next Man Up culture. A leader leaves, and suddenly the whole department collapses. A key employee gets sick, and the project halts for weeks. A decision is delayed because “the boss isn’t in today.”
These are amateur failures. They are entirely preventable. They are a sign of poor leadership and weak culture.
Contrast that with the military: leaders get killed in action, radios get destroyed, comms fail, and yet the operation continues. Why? Because Next Man Up isn’t optional. It’s ingrained.
If you’re a veteran stepping into corporate America, here’s the hard truth: most people have never lived Next Man Up. They’ve never been expected to lead without notice. They’ve never been cross-trained to carry another’s load. They’ve never been asked to step up in the middle of chaos.
That’s your advantage. You bring a mindset that companies desperately need, even if they don’t realize it. But, caution, you have to translate it.
Don’t walk in barking orders about the chain of command. Don’t lecture people on how weak they are compared to your old unit. Instead, model the new behavior. Be the one who steps up when someone’s absent. Be the one who mentors replacements. Be the one who runs the AAR when everyone else wants to celebrate and move on.
Over time, people will notice. Leaders will see it. Teams will adopt it. And you’ll have built buy-in the same way we did in uniform. Through example, not ego.
If you’re leading a team, here are five actions you can take immediately to bring Next Man Up into your organization:
Make Cross-Training a Requirement: Every employee should have a baseline understanding of at least one adjacent role. Document it, train it, test it.
Reward Redundancy, Not Hoarding: Stop promoting the guy who hides knowledge to stay indispensable. Promote the one who builds capability in others.
Institutionalize AARs: After every project, make it a ritual. Not optional. Share lessons learned widely.
Stress Test Roles: Don’t wait for emergencies to find out who can step up. Build it into training. Surprise assignments, rotating leadership, sudden hand-offs.
Celebrate the Step-Ups: When someone fills in and delivers, make it visible. Recognition fuels repetition.
When you build a culture of Next Man Up, you get three priceless assets:
Engagement: Everyone stays plugged in because they know they matter.
Buy-In: People own not just their tasks, but the operation.
Resilience: Your organization doesn’t crack when one piece fails.
That’s what makes special operations teams effective. That’s what can make your business unstoppable.
For those of us who wore the uniform, Next Man Up isn’t negotiable. It’s the reason we came home alive. It’s the reason operations succeed against impossible odds. It’s the reason teams bond into families.
In your transition, don’t leave that philosophy behind. Carry it with you into your next chapter.
Show your civilian colleagues that leadership isn’t about title: it’s about responsibility.
Show your team that buy-in isn’t about slogans: it’s about action.
Show your company that resilience isn’t built in boardrooms: it’s built when everyone is ready to be the next man up.
Because here’s the truth: in the real world, just like in combat, the operation won’t wait. The question is: when it’s your turn, will you be ready to step up?
