Let me tell you a story. Not the kind you hear around a campfire. This one has warships sinking, generals throwing tantrums, and scripted victory sequences that would make a Hollywood movie director weep. It’s the tale of Millennium Challenge 2002 (MC02) the U.S. military’s most expensive war game in history and why the lessons from it should haunt every cyber drill planner worldwide.
Picture it: summer 2002, early days of the post-9/11 era. The U.S. military set up a gigantic war game involving 13,000+ personnel, computer simulations, live field exercises, and a jaw-dropping $250 million price tag the most expensive military exercise ever at that point.
This wasn’t a paintball game with camo and velcro targets. This was supposed to test the future of network-centric warfare where real-time information and technology dominance make you untouchable. The plan looked solid on paper but reality had different ideas.
The Red Team That Stole the Show
Enter retired Marine Corps Lieutenant General Paul Van Riper, leading the “Red Team” (i.e., the enemy). Van Riper was a combat veteran who was twice awarded the Silver Star for his heroic actions during the Vietnam War. While the “Blue Team” (the fancy, high-tech U.S. forces) was busy streaming data across networks and checking GPS overlays, Van Riper had a simpler idea: go rogue.
Instead of playing by the “modern tech” rulebook, he took his Red Team offline. Literally. They passed orders via motorcycle messengers (think traditional couriers), used light signals for coordination, and avoided electronic communications that the Blue Team was counting on.
Then the exercise began in earnest. Red opened with a cruise missile barrage, followed closely by a swarm of small boats. They sank most of the Blue fleet in literally minutes using asymmetric tactics that the Blue commanders never anticipated.
If this were cinema, the orchestra would sound a dramatic chord here. Think Mission: Impossible meets Pirates of the Caribbean.
The Unsatisfying Scripted Ending
Here’s the moment every cyber consultant will hate: rather than learn from the exercise, the planners paused the war game, put the Blue Team back in a position where they could win and forced the Red Team into a scripted, predictable role. Basically they cheated.
Why? Officially, the rationale was that a quick Red victory meant the exercise would be over too soon and there wouldn’t be time to train all those hundreds of troops and technicians. And so the solution? Don’t fix the exercise; fix the rules.
Yes. That’s like giving someone a cheat code so you win even when you’re losing. Great for your ego but terrible for actual learning.
So What Does This Have to Do With Cybersecurity?
Quite a lot. In fact, if you replace warships with servers and missiles with malware, MC02 becomes a parable for cybersecurity drills everywhere.
1. Real Threats Don’t Read the Script
In Millennium Challenge, the Red Team’s approach was unconventional and something the planners didn’t expect because they assumed the enemy would fight “their way.”
In cybersecurity, threats don’t fight how we expect.
- A phishing attack might come from inside your own company.
- A ransomware operator might use old vulnerabilities patched years ago.
- Zero-day exploits might pop up where you least expect them.
Cyber attackers don’t follow a neat, scripted playbook so why should your drills?
A drill that only tests expected threats is like a war game where victory is assigned ahead of time. It’s training for confidence, not competence.
2. Overreliance on Tools Can Be Dangerous
Blue Team in MC02 assumed their tech would save the day as they had network-centric plans, real-time sensors, and automated systems. Yet the Red Team bypassed all of it with low-tech ingenuity.
In cybersecurity, I see the same thing:
- Teams lean on SIEM alerts to catch everything.
- Organizations trust antivirus to block all malware.
- Companies depend on frameworks without verifying real world efficacy.
But all the flashy dashboards and automated detection in the world won’t help if someone or something finds a way around them.
Effective drills must test what happens when the tech fails, or when attackers ignore our rules, or when our assumptions blow up in real time.
3. Drills Should Teach Us, Not Validate Us
One of the biggest criticisms of MC02 was that after Van Riper’s stunning performance, the military responded not by absorbing the lesson but by burying it under a scripted replay.
That’s like doing a cyber breach simulation and only celebrating if your team “wins”. It doesn’t matter how unrealistic the attacker was.
In the real world, if your red team stomps your blue team in a drill, that’s not a defeat. That’s a learning opportunity. But only if leadership is humble enough to say, “Whoa. We missed something.”
That humility is rare especially when budgets, egos, and organizational politics get involved. Yet it’s exactly what separates mature security programs from expensive theatre.
4. Creativity and Asymmetry Matter
The Red Team’s success at MC02 was a classic example of asymmetric tactics using creativity and unpredictability to exploit assumptions.
Today’s cyber threats use the same approach:
- Multi-stage social engineering that starts with LinkedIn.
- Supply chain compromises that begin with tiny vendors.
- Hybrid attacks that mix automated bots with human decision making.
If your drills only test standard scenarios like “attacker uses phishing then APT toolkit X”, you are leaving yourself vulnerable to the modern equivalent of motorcycles and light signals.
Training against predictable attacks is like preparing for chess when your opponent plays 3-D checkers.
5. Invest in Good Adversary Emulation, Not Scripted Games
Here’s the bottom line: a drill that ensures the “defenders” always win is expensive entertainment and not training.
A proper cyber drill should:
- Allow the adversary (red team) to think creatively.
- Test people, process, and technology under pressure.
- Reveal assumptions and not confirm them.
- Surface gaps and not hide them behind scripted outcomes.
That’s how real improvement happens.
Final Thoughts
If Millennium Challenge 2002 teaches anything aside from never angering a retired general with a mischievous grin, it’s that real learning doesn’t come from winning scripted battles. It comes from confronting the unexpected and adapting.
We in cybersecurity should take that to heart. Next time you plan a drill, don’t be the Blue Team that insists on a happy ending no matter what. Be brave. Let the drill surprise you. Let it show you where your firewalls are leaky, where your alerts are blind, and where your assumptions are just that assumptions.
Because in the real world, attackers aren’t playing by your rules.
And neither should your drills.
See you in the next blog post :-)
