The Explosion Corps: Iwagakure's Demolition Unit

What the series actually says about the unit

The Explosion Corps is an organization of Iwagakure. Its Japanese name, Bakuha Butai, describes a unit of destruction. The English television version rendered it as "Demolitions Unit", that is, a unit for demolition. Its purpose is therefore legible from the name itself: to open breaches, bring down structures, make a terrain untenable.

The series remains stingy, though. Only two members are named: Gari and Deidara. Both master the same kekkei genkai, Explosion Release. No scene shows the corps in training, nor its strength, nor its chain of command, nor the slightest distinctive uniform.

This discretion calls for caution. You sometimes read that the unit fielded specialists in scrolls and explosive tags: that detail comes from later compilations, not from the story itself. The question of command, on the other hand, is settled differently depending on the medium: the manga simply makes Gari a member of the corps, while the anime presents him as its former leader. What the manga establishes fits in a few words: Iwagakure maintained a cell dedicated to firepower, and its two known faces carried a rare bloodline.

Bakuton, the Explosion Release

The Bakuton, or Explosion Release, is a kekkei genkai: a bloodline, not a technique that can be learned. Its bearer charges a material, or the opponent's body, with an explosive chakra that he sets off at the moment of his choosing. The corps fields both of its schools: Gari strikes up close and makes his target detonate from the inside, while Deidara kneads his chakra into clay and strikes at range, with a delay he controls.

Since both named bearers come from Iwagakure, the idea of a bloodline unique to the Hidden Stone Village took hold. A side story nevertheless features an Explosion Release user whose village is never identified: a likely monopoly, not a proven one. Its assumed composition and its weak points, for their part, belong to Explosion Release, not to the unit.

Deidara, the corps' unstable element

Deidara serves in the Explosion Corps before betraying it. He arrives there with the Bakuton and an obsession that has nothing to do with military discipline:art. His clay sculptures are praised in the village, but that recognition is never enough for him.

So he steals a kinjutsu from Iwagakure, a forbidden technique that makes it possible to knead chakra into a material. Applied to himself, it opens a mouth in each palm, plus another, stitched shut, on his chest. Combined with his kekkei genkai, it yields explosive clay, his signature.

Desertion follows. His pursuers serve as a demonstration: he wipes them out with his clay and considers that he has finally touched absolute art. Now an S-rank rogue ninja, he hires out his bomb-making skills to insurgents in several countries, before being forced to join the Akatsuki, of which he becomes the youngest member.

The tie with Iwagakure does not break cleanly, though. Onoki, the Third Tsuchikage, had spent time around him in the village and knew his fighting style well enough; he made no secret of his frustration that a kid like Sasuke had been able to finish him off. Kurotsuchi, the latter's granddaughter, calls him "big brother". A traitor, then, but a traitor the village never entirely erased from its memory.

Iwagakure's doctrine and wartime use

Iwagakure built its reputation on Earth Release and on a school of solidity. A demolitions unit extends that logic through its opposite: what stone protects, explosion opens. The Third Great Ninja War, which harshly pitted Iwagakure against Konoha, sheds light on this pursuit of firepower. Facing opponents like Minato Namikaze, capable of tearing apart entire battalions and of prompting flee-on-sight orders, an area-destruction capability keeps all its value.

Gari belongs to an earlier generation and dies before the final conflict. His death does not remove him from the story, however. Kabuto Yakushi brings him back through the Edo Tensei (Reanimation Jutsu) for the Fourth Great Ninja War. The anime specifies that Orochimaru coveted his DNA and congratulated Kabuto for bringing back a sample: the Bakuton is collected like a rare weapon.

Reanimated, Gari is deployed alongside Zabuza, Haku, Pakura and Toroi. The group first runs into the Allied Shinobi Forces' surprise-attack unit, then into the Third Division led by Kakashi. It is the only moment when the corps' know-how is displayed on a large-scale battlefield.

Deidara comes back as well. Assigned to the surprise-attack and diversion unit with Sasori, he is given the mission of throwing the Allied Shinobi Forces into disarray with explosives. He ends up captured by Kankuro's team. Two veterans of the same corps, brought back from the dead, turned against their own side: Iwagakure's firepower will above all have served the enemy.

FAQ

• How many members does the Explosion Corps have?
  The series names only two, Gari and Deidara. Its actual strength, its command and its organization are never specified in the story.
• Is Explosion Release exclusive to Iwagakure?
  Both named bearers come from there, which makes the hypothesis credible. A side story does show a user whose village is not identified, however: it is better to speak of a very strong association than of proven exclusivity.
• Was Deidara born with his explosive clay?
  No. He had Explosion Release, but the clay comes from a forbidden technique stolen from his village, which allows chakra to be kneaded into a material and left him mouths in his palms.
• Why did Deidara leave the village?
  His quest for absolute art drove him to steal the kinjutsu, then to flee. He then sold his bomb-making services to insurgents before being forced to join the Akatsuki.
• Did Gari and Deidara serve together?
  Nothing indicates it. No scene brings them together and the story does not date their respective terms of service: Gari died before the Fourth Great Ninja War, where he reappears reanimated.

In summary

The Explosion Corps takes up very little room in the story, and that is precisely what makes it interesting. Two men, a rare bloodline, a doctrine you sense more than you read. The unit still illuminates Iwagakure better than any long speech: a village that bets on stone needs, in mirror image, to know how to break it. Above all it illuminates Deidara, whose entire arc consists of turning a military tool into an artistic gesture. From that shift comes a rogue ninja, then a member of the Akatsuki. The rest, the series deliberately leaves in shadow.
