Weapon Defence

Group

武器防御(Buki Bōgyo)

Traditional

Translation: weapon defence

Overview

The Weapon Defence group encompasses defensive techniques against armed attacks, including knife defence, gun defence, and stick/baton defence. [1] Weapon defence is the most serious self-defence scenario because armed attacks carry the highest risk of lethal injury — the defender must neutralise the threat of the weapon while managing the extreme danger of close-range engagement with an armed attacker. [1],[2] This group addresses the three most common weapon categories encountered in self-defence situations: edged weapons (knives), firearms (guns), and impact weapons (sticks, batons). [2],[3] It is important to note that all weapon defences carry significant risk and the primary recommendation in any armed encounter is to escape if possible. [3]

History & Origin

Weapon defence techniques have been taught in martial arts since antiquity, with Japanese jujutsu systems including specific kata for defending against sword, knife, and staff attacks. [1] Filipino martial arts (Kali/Escrima/Arnis) developed the most comprehensive weapon defence curriculum, treating weapon defence as inseparable from weapon offence. [2] Modern self-defence systems like Krav Maga, developed for the Israeli military by Imi Lichtenfeld, systematised weapon defence for modern threats including firearms. [2],[3]

Effectiveness

Weapon defences are self-defence techniques designed to neutralise attacks from armed assailants, including knife, gun, and stick threats. [1],[2]

Lineage

Weapon defences are found in many martial arts including Krav Maga, Filipino martial arts, and traditional jujutsu. [1],[2]

Competition Record

Weapon defence is primarily a self-defence discipline; it is not typically featured in sport competition. [1]

Biomechanical Mechanism

Primary ActionPreventing or reducing the effect of an incoming attack through physical interception, evasion, or structural positioning
Joints InvolvedVaries by defence type — blocks use arms/shins, evasions use head/body movement, sprawls use hips
Force VectorOpposing or tangential to the attack — either absorbing, redirecting, or evading the incoming force
Defensive PrincipleEconomy of motion — the best defence uses minimal movement to neutralise the maximum threat

Position & Entry

From opponent's armbar attemptClasp the hands together (gable or S-grip), stack the opponent by driving forward, posture up and pull the arm free
From early attackBefore the submission is locked, fight the grips and posture to prevent the arm from being fully extended

Training Notes

Weapon defence addresses threats from knives, guns, sticks, and improvised weapons — these are self-defence and military combatives techniques, not sport applications
The first and best weapon defence is avoidance and escape — if you can run, run; no technique is reliable against an armed attacker
If escape is impossible, the priority sequence is: (1) control the weapon/weapon hand, (2) create distance or disarm, (3) neutralise the attacker
Weapon defence requires understanding the specific threat: edged weapons (knives) require different tactics than impact weapons (sticks) and projectile weapons (guns)
Realistic weapon defence training uses padded training weapons at increasing resistance — compliant drills create false confidence
Krav Maga, military combatives (Fairbairn, Sykes), and Filipino martial arts (Pekiti-Tirsia, Kali) are the primary systems for weapon defence
Accept that weapon defence will likely result in injury — the goal is survival, not perfection; any defence that saves your life is a success

Common Mistakes

!Believing weapon defence techniques work perfectly in real situations — real weapon encounters are chaotic; techniques reduce risk but don't eliminate it
!Training only against compliant attacks — a real attacker won't stand still or use a single slow strike
!Attempting to disarm without first controlling the weapon hand — the weapon hand must be secured before any disarm
!Not training with realistic resistance and protective equipment — adrenaline, speed, and aggression change everything
!Underestimating edged weapons — a knife attacker can inflict fatal wounds in seconds; treat every knife encounter as life-threatening
!Defending a gun from too far away — gun defences only work at contact distance; at range, compliance may be safer
!Over-confidence from martial arts training — no amount of empty-hand training guarantees success against a weapon

Sub-techniques

Fencing Parry

Family

The Fencing Parry family covers the system of blade deflections used in fencing to redirect an opponent's attacking blade away from the valid target area — the sword-fighting equivalent of blocking in unarmed combat, but executed with the blade itself. [1] Modern fencing recognises eight primary parries (prime through octave), each protecting a specific sector of the body by positioning the blade to intercept attacks from different directions. [1,2] Parries are the foundation of defensive fencing and are always followed by an immediate riposte (return attack) — the parry-riposte sequence is fencing's fundamental defensive-offensive unit, conceptually identical to the block-counter in boxing. [2,3] The parry system was formalised in the French and Italian fencing schools of the 17th–18th centuries and remains the standard teaching methodology in modern Olympic fencing across all three weapons (foil, épée, sabre). [3]

Gun Defence

Family

The Gun Defence family covers defensive techniques against firearm threats, including disarms and redirections at close range. [1] Gun defence is the most extreme self-defence scenario and should only be attempted when escape is impossible and the threat of harm is imminent — compliance is generally the safest response when avoidance is not possible. [1,2] Gun defence techniques focus on redirecting the muzzle away from the body, controlling the weapon hand, and executing a disarm before the attacker can fire or recover control. [2,3]

Knife Defence

Family

The Knife Defence family covers defensive techniques against edged weapon attacks, including slashing and stabbing attacks with knives, blades, and other edged weapons. [1] Knife defence is extremely challenging because edged weapons require minimal skill to inflict serious injury, the attacker can change angles rapidly, and the defender is likely to sustain cuts even in a successful defence. [1,2] Knife defence techniques focus on controlling the weapon hand, redirecting the blade, and creating distance or executing a disarm when escape is not possible. [2,3]

Krav Maga Defence

Family

The Krav Maga Weapon Defence family covers techniques for defending against armed attacks — knife threats, gun threats, stick attacks, and other weapons — designed for life-or-death self-defence scenarios where disengagement is not possible. [1] Krav Maga weapon defences follow a strict protocol: (1) redirect the weapon away from the body, (2) control the weapon arm, (3) deliver aggressive counter-strikes to neutralise the attacker, and (4) disarm if possible. [1,2] Unlike martial arts that teach weapon 'sparring' or 'matching' (fighting weapon vs weapon), Krav Maga assumes the defender is unarmed against an armed attacker — the worst-case scenario — and provides techniques designed to survive this encounter. [2,3] These techniques are the most dangerous to train and the most critical to know, as armed attacks are among the most lethal threats civilians and military personnel face. [3]

Stick Defence

Family

The Stick Defence family covers defensive techniques against impact weapon attacks, including sticks, batons, clubs, and similar blunt instruments. [1] Stick defence addresses the challenge of defending against a weapon that extends the attacker's range and can deliver bone-breaking force on impact. [1,2] Defensive strategies focus on closing distance to reduce the weapon's effectiveness (impact weapons lose power at very close range), blocking or deflecting at the weapon hand rather than the weapon itself, and executing disarms or controls that neutralise the threat. [2,3]

Notes

Weapon defense — against knives, guns, sticks, and edged weapons — is the highest-stakes self-defense category. Knife defense appears in 261 passages across 39 books. The universal expert consensus: the best defense against a weapon is to escape. When escape is impossible, control the weapon hand first. (39+ books; Krav Maga manuals; FMA texts; military combatives)

Frequently Asked Questions

What's the key principle for defending against weapons attacks?

Matt Numrich teaches the DDP-IT framework: Distancing, Distraction, Pain, Isolation, and Termination. These are tactical options you can use individually or in combination to neutralize a weapon threat.

How important is distance when defending against a knife or stick?

Distance is critical—you need to find the correct range where you won't get cut or struck even if the attacker swings. Matt Numrich emphasizes training with a partner using a training weapon to develop feel for how far is too far and how close is too close.

What should I do after isolating the weapon?

Once you isolate the weapon and attacker's movement, use 'heavy artillery'—elbows, knees, and headbutts—to control the situation. Matt Numrich advises softening the person up with knees and headbutts first rather than immediately letting go to strike, which would free them to fight back.

If someone has a gun pointed at me, should I immediately try to disarm them?

No—Code Red Defense teaches that de-escalation and verbal negotiation should come first. Use psychology and dialogue to lower the attacker's guard and raise awareness, since a nervous attacker might accidentally shoot if you flinch.
