A karate practitioner traded his traditional dojo for a tactical facility in an undisclosed location, where he trained with Navy SEAL Kenny “Big B” Jr. to learn combat concepts that could save his life.
The experience wasn’t just about fighting—it was about surviving.
Jesse Enkamp, known in martial arts circles as “the karate nerd,” discovered that decades of traditional training hadn’t prepared him for the chaotic reality of real-world violence.
What he learned in a single day would fundamentally change how he understood combat.

Fighting By Concept, Not Technique
Kenny introduced a revolutionary approach that contradicts traditional martial arts training. Instead of memorizing hundreds of individual techniques, he teaches universal principles that emerge across all effective movements.
We should fight by concept and not by technique. We need to make clarity out of chaos.
Kenny compared this to molecular patterns in chemistry. Individual molecules appear random, but groups reveal consistent structures. Similarly, different throws share the same footwork, fulcrum, and lever mechanics—they’re variations of one concept, not four separate techniques.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
This pattern-recognition approach allows fighters to respond instinctively under stress, when detailed technique recall becomes impossible.
The Bisecting Line: Your First Line of Defense
Kenny’s first combat concept was deceptively simple: bisecting lines.
Think of a plus sign intersecting your opponent’s attack trajectory. Whether defending against punches, kicks, or knife strikes, these perpendicular blocks redirect force while keeping you protected.
Jesse tested this against various attacks—jabs, crosses, hooks, and leg kicks. Every time, the bisecting line principle worked regardless of the specific strike.
But defense alone doesn’t win fights.
You Can’t Win On Defense
What game can you win on defense? You cannot lose. Exactly. You can only win through offense.
Kenny emphasized the critical importance of transitioning from reacting to acting. In survival situations, prolonged defense guarantees eventual failure. Attackers maintain initiative, choosing when and how to strike.

The warrior mindset requires shifting to offense as quickly as possible, forcing opponents into defensive reactions.
This isn’t about reckless aggression—it’s about controlled counterattack that changes the dynamic of engagement.
Inside Lines vs. Outside Lines
Kenny distinguished between two defensive approaches with dramatically different outcomes.
Inside lines deflect attacks but leave you facing multiple threats. Your opponent’s other hand, elbows, knees, and head remain dangerous.
Outside lines move you toward your opponent’s back, where all their weapons go offline simultaneously. Even apex predators like tigers instinctively attack from behind—their prey can’t defend what they can’t see.
All of fighting is getting your tools online and my tools are offline.
Jesse practiced redirecting punches and kicks to outside lines, consistently ending in dominant positions where counterstrikes faced no opposition.

Three Layers of Training
Kenny outlined a progressive training methodology that most traditional martial artists never complete:
Technical Training (Peak Performance)
Perfect form under ideal conditions. Flawless body mechanics optimize muscle recruitment and movement efficiency. This establishes the baseline for what’s physically possible.
Tactical Training (Finding Opportunity in Chaos)
Applying techniques against resisting opponents who don’t cooperate. It’s messy, exhausting, and realistic. Fighters learn to recognize fleeting opportunities within combative chaos.
That’s the problem with how some of the traditional martial arts are trained. The technique is there, but they don’t practice it under chaos and find the opportunity in the chaos.
Tenacity Training (Optimal Performance Under Duress)
Executing skills while exhausted, injured, or psychologically stressed. This represents actual combat conditions where adrenaline, fatigue, and fear degrade performance.
The Hidden Effectiveness of Traditional Forms
Kenny demonstrated how ancient martial arts contain sophisticated combat concepts—if practitioners understand what they’re actually looking at.
He showed Tai Chi movements that appear mystical but represent practical arm locks and sweeps. Karate kata techniques that seem decorative actually teach off-balancing and joint manipulation.

- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
The problem isn’t the traditional arts themselves—it’s training methodology that never progresses beyond technical perfection into tactical application.
When Jesse asked about a particular Tai Chi sequence, Kenny immediately applied it as a leg-catch counter, then demonstrated the same principle from Muay Thai. Different arts, identical concept.
Blade Defense Under Stress
Training escalated when Kenny introduced shock knives—training weapons that deliver electric jolts on contact.
Jesse’s mission: apply combat concepts against knife attacks without getting “cut” (shocked). The bisecting lines that worked against punches proved equally effective against blade thrusts and slashes.
But Kenny added complexity: after defending, Jesse had to establish a two-on-one grip (both hands controlling the weapon arm), then transition to an outside line for counterattack.
This layering of concepts—defend, control, dominate—mirrors real violence where single techniques rarely resolve situations.

Ground Fighting With Weapons Changes Everything
Kenny revealed a critical flaw in traditional Brazilian Jiu-Jitsu when weapons enter the equation.
Standard arm-bar and Americana submissions require two hands controlling one arm. But when defending against a knife, this natural hand-grouping allows attackers to transfer the blade to their free hand—now completely uncontrolled.
The Navy SEAL solution: separate the hands.
Using a topside crucifix position, Kenny trapped Jesse’s weapon arm with his shin while pushing the opposite arm overhead. This maximized Kenny’s muscle recruitment (chest and lats) while minimizing Jesse’s (bottom of pull-up position).
I want to maximize my resources and minimize your resources. That’s a broadstroke emerging concept.
When separation proves impossible, trapping the weapon hand to the ground or body buys critical seconds for tactical disengagement.
Why Mount Position Becomes Dangerous With Weapons
Kenny challenged another sacred MMA concept: mount superiority.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
In unarmed combat, mounted ground-and-pound dominates. But in weapons-based environments, mount position creates vulnerability. Attackers on their backs can easily access concealed weapons while defenders commit both hands to striking.
During pummeling drills, Kenny demonstrated how losing position triggers weapon deployment. Fighters winning exchanges rarely expect losing opponents to introduce blades—creating devastating surprise attacks.
Always assume weapons presence fundamentally changes tactical decisions.
Tactical Disengagement vs. Running Away
Kenny distinguished between cowardly retreat and strategic repositioning using historical examples.
Genghis Khan’s cavalry would feign retreat, drawing enemies into killzones where surrounding forces engulfed them. Alexander the Great opened Greek phalanx lines, allowing attackers to penetrate before enveloping them from all sides.
Modern application: when grounded with weapon disadvantage, create space to re-engage from superior positions rather than competing where you can’t win.

We have a saying in the teams—if you’re not cheating, you’re not trying. That just means gain the tactical advantage.
The Warrior Mindset: Until
Kenny distilled survival psychology into one word: until.
I keep fighting until I am too tired to fight. Until I’m out. I keep fighting until I’m out of the fight. I keep fighting until I’m free. I keep fighting until I’m victorious.
This simple mental framework instills hope and indomitable spirit—qualities traditional martial arts emphasize but rarely pressure-test.
“Until” provides psychological endurance when physical resources deplete. It transforms “I can’t continue” into “I continue until I physically cannot.”
The Field Training Exercise
Jesse’s final test combined everything: an obstacle course completed three times with combat engagements after each lap.
Round one required catch-and-shoot defense transitioning to two-on-one control and outside lines. Round two added pummeling from over-hooks and under-hooks. Round three integrated all concepts against Kenny himself—the final boss.
Jesse struggled through rope climbs that destroyed his grip strength, conquered heights despite exhausted legs, and fought while gasping for air. His technique degraded from peak performance to optimal performance—doing his best with diminished capacity.

But the concepts held. Bisecting lines still deflected attacks. Outside positioning still created openings. The principles worked even when perfect execution became impossible.
From Perfection to Protection
Kenny praised Jesse’s adaptation during the final evolution. Unable to execute the exact prescribed sequence, Jesse improvised using the same underlying concepts—exactly what real combat demands.
We went from perfection, which is peak performance, to protection, which is optimal performance. When it gets crazy and you make clarity in the chaos, he made the concepts work and made it happen. That’s how it goes in the real world.
This distinction represents the gulf between traditional training and functional combatives. Kata perfection matters less than conceptual understanding under duress.
Key Takeaways for Martial Artists
- Learn concepts, not just techniques. Patterns that emerge across multiple situations prove more reliable than memorized responses.
- Transition from defense to offense immediately. Prolonged defensive posture guarantees eventual failure.
- Train under chaos and fatigue. Technical perfection means nothing without tactical application under stress.
- Always assume weapons. This assumption changes positional priorities and risk assessment.
- Separate rather than group hands in weapons-based grappling to maintain control of dangerous limbs.
- Embrace tactical disengagement. Strategic repositioning isn’t cowardice—it’s intelligent resource management.
- Adopt the “until” mindset. Psychological endurance often outlasts physical capability.
Jesse left with more than techniques. He gained a framework for making clarity from chaos—a cognitive shift that transforms how martial artists prepare for situations where survival, not scoring points, determines success.
His honorary “Killer B” patch symbolized that transformation: from traditional practitioner to someone harder to kill.
