Introduction to Jinjun Saljukse

Jinjun Saljukse, translated as the Lunge and Kill Posture, is a fundamental technique in the Jedok Geom (Admiral's Sword) form from the Korean Joseon Dynasty. This technique comprises two distinct components: the lunge footwork and the killing strike, each serving specific tactical objectives in combat.

Footwork Mechanics: The Lunge

The lunge refers to explosive forward footwork executed from either right or left long stance. The movement should be a rapid, gliding skip step that propels the body forward with maximum power while maintaining ground contact—avoiding upward jumping or downward stomping that dissipate energy inefficiently.

Distance Variations: Short vs. Long Steps

Practitioners can execute the skip step as either a short, controlled advance that adds power to the strike without excessive forward movement, or as a longer gap-closing step that closes distance on an opponent. Both variations serve to transfer body mass forward into the subsequent cut.

Left Stance Execution

When performing Jinjun Saljukse from left long stance, the technique shifts to an alternating step where the right foot propels forward with powerful drive from the left leg. This creates effective mass transfer despite the non-dominant positioning, though right long stance is preferred to leverage dominant-side power advantages.

The Kill Strike: Weapon Technique

The killing stroke typically manifests as a vertical head cut in traditional Korean practice, though a diagonal downward cut to the left side is equally valid given the head's protective skull and common helmet usage in historical combat. This differs fundamentally from the Kyukjukse basic attack posture in its power-first approach.

Power Priority and Follow-Up Options

Unlike the Kyukjukse, where follow-up options are prioritized, Jinjun Saljukse emphasizes maximum strike power as the primary objective, with post-strike options as secondary consideration. The entire body weight must drive forward into the cut for optimal effectiveness—arm strength alone cannot compensate for lacking body mass.

Tactical Application: Exploiting Openings

Jinjun Saljukse proves most effective when exploiting sudden tactical opportunities during dueling, such as when an opponent's blade extends past the defender after their own strike. The technique functions as an immediate gap-closer allowing the practitioner to seize initiative and strike before the opponent can react.

Battlefield Application and Chase Tactics

On the battlefield, this technique enables practitioners to exploit inattentive opponents or pursue retreating enemies. The double Jinjun Saljukse sequence documented in the Jedok Geom toro represents a chasing attack pattern designed to overwhelm opponents, force repositioning, or create openings through relentless forward pressure.

Practice Recommendations

Practitioners unfamiliar with Jinjun Saljukse should practice using a bokken (wooden training sword) to safely develop proper footwork, distance management, and power transfer. Detailed documentation of the Jedok Geom toro with interpretive notes is available to practitioners seeking deeper technical understanding of this essential technique.

Welcome to the Jedok geom series where I break down the Admiral's sword form and show you the stances and my interpretation of them. I'm not an expert so feel free to disagree with my conclusions, these are just what I have found to work well for me. In today's episode we talk about the Jinjun Saljukse, the lunge and kill posture. It is a powerful strike with a fast gap closer used to seize an opportunity in battle.
