Abilities & Tactics

Earth Release

Earth Release supports both infiltration and battlefield defense 29 96 177.

• Underground movement: More than thirty attackers approach beneath Konoha’s formation to strike its center and expose newly promoted Genin 29.
• Subterranean ambushes: Techniques include dragging opponents underground, splitting the ground, and producing lethal spikes 29 43.
• Defensive applications: Troops use body hardening and large earthen walls, although the Third Raikage and Yechen demonstrate the ability to break through them 96 177.
• Withdrawal: Earth Release enables coordinated retreats and individual escapes 31 148.

Combined Attacks and Encirclement

Rock Ninja repeatedly coordinate attacks to restrict enemy movement and prevent retreat 114 119 145.

• Formation disruption: Attackers use Konoha Genin as cover, preventing allied Chunin from safely employing wide-area techniques 29.
• Layered ambushes: A road attack combines kunai volleys with three Great Dragon Fire Technique blasts 35.
• Close-combat coordination: Three fighters maintain relentless pressure on Yechen, attempting to create and exploit an opening 114.
• Three-direction blockades: Forces approach from the front and both flanks to complete an encirclement 145.
• Deceptive deployment: Familiar attack routes conceal a more effective assault, with Roshi’s arrival contributing to the rapid collapse of Konoha’s central line 167.
• Combined defense: Earth- and Water-style techniques are layered against Yechen’s sea of flames 177.

Sensory Operations and Investigation

Specialists support pursuit and counter-infiltration, but Yechen’s disguises and clones repeatedly undermine them 96 97 174.

• Anbu investigation: Investigators identify an enemy impersonator after reports of apparent Rock Ninja infighting and sabotage at a wounded-soldiers’ camp 96.
• Extended tracking: Eiko’s sound-based sensing and bat summon locate threats beyond the range Yechen initially checks with his Byakugan 97 98.
• Hostility detection: Roshi exposes Yechen despite acknowledging that his transformation is visually flawless 169.
• Clone vulnerability: A sensor mistakes Yechen’s Shadow Clone for his real presence while the original attacks troops elsewhere 174.

Jinchūriki and Sealing Teams

Han and Roshi provide destructive power beyond that of ordinary squads, while sealing specialists serve as safeguards against loss of control 129 176.

• Han: Steam acceleration, a defensive cloak, and a horn make his charging attacks dangerous even to opponents who are merely grazed 129.
• Roshi: Tailed Beast Bombs and Lava Release threaten entire defensive positions; his lava armor also endangers nearby Rock Ninja, forcing them to scatter 153 170.
• Sealing support: Han’s escorts are primarily assigned to reseal the Five-Tails. Their limited direct-combat experience leaves them vulnerable to Yechen 129.
• Emergency containment: Troops prioritize Roshi’s loss of control over pursuing withdrawing Konoha forces, then attempt to seal the Four-Tails back into him 176 177.

History

Early Fighting Against Konoha

Rock Ninja launch an underground attack on Konoha’s Genin formation, aiming to disrupt its center and spread casualties. Yechen counters their concealed approach, killing several Chunin before stronger opponents intervene. Two Special Jōnin attempt to unsettle him with an offer to join Iwagakure, but he recognizes it as a ploy. The force subsequently withdraws under coordinated signals 29 30 31.

They later surround Branch 16 and ambush Konoha troops on the road. The wider joint Rock and Sand attack badly damages Konoha’s camp and kills seven Jōnin, delaying its ability to respond 33 35 41.

Konoha retaliates with a surprise attack on a frontline Rock Ninja outpost. Underground defenders kill and injure approaching Genin, while guards inside the stronghold resist the assault. A captured Genin reveals that the supply warehouse is beneath the village center 43 44.

Encirclement of Kumogakure

During Konoha’s intelligence mission in the Land of Earth, Yechen observes Iwagakure fighting an elite Kumogakure force led by the Third Raikage. He later sabotages a wounded-soldiers’ camp; Iwagakure initially blames Kumogakure, while Yechen infiltrates the retreating Cloud force 86 92.

The Rock Ninja surround Kumogakure, but the Third Raikage continues fighting for three days. Nearly three thousand Rock Ninja die, many more are wounded, and Ōnoki himself is injured. The Raikage eventually exhausts his chakra, creating the opening Yechen uses to subdue and carry him away 92 93 96 97.

Yechen’s intervention ruins Ōnoki’s months-long plan to cripple Kumogakure. Ōnoki orders elite squads and Chunin teams to pursue him, then seals major routes through the Lands of Earth, Rain, and Fire. Despite these measures, Yechen hides near Iwagakure, and a month-long search fails to locate him or the Raikage 97 100 101.

Renewed Blockades and the Loss of Han

During later fighting, a wounded Rock Ninja identifies Yechen as the spy responsible for taking the Third Raikage. Yechen kills him and destroys his message before the information can be transmitted 115.

Rock Ninja continue converging on Konoha forces. One encirclement involves roughly five hundred attackers against more than three hundred Konoha troops, with further reinforcements expected. Yechen’s attacks create openings, but do not remove the surrounding threat 118 119.

Han subsequently ties down several Konoha Jōnin while accompanying Rock Ninja support the battle. Yechen separates Han from his escorts, defeats the sealing specialists, and later overwhelms the jinchūriki. Han’s death is explicitly acknowledged before Roshi’s later confrontation with Yechen 129 132 134 169.

Willow Town Offensive

Roshi opens the Willow Town assault with a Tailed Beast Bomb, but Minato redirects it away from the stronghold. Iwagakure then advances in three groups, including more than a hundred troops approaching the western heights defended by Yechen 153 154.

Konoha infiltrates the Rock Ninja stronghold and attacks its command center. Kuroki Masayasu organizes resistance, while Yechen kills Hunt and numerous supporting fighters. The devastating command-center casualties provoke a fierce Rock Ninja retaliation involving Roshi 157 158 159 160 166.

The ensuing night battle exhausts both armies. With their command disrupted, the Rock Ninja shift to defense; Konoha is too depleted to exploit the opportunity 166.

Loss of Roshi and Military Decline

A renewed Rock Ninja offensive uses a familiar three-force deployment as a smokescreen. Roshi’s breakthrough inflicts severe losses on Konoha, but Yechen attacks the Rock Ninja rear, forcing him to halt his advance and return 167 169 174.

After Roshi loses control, the Rock Ninja attempt to reseal the Four-Tails. Yechen breaks their defenses and barrier, attacks the sealing personnel, and takes the beast away. Intelligence subsequently confirms Roshi’s death 176 177 181.

The loss of both jinchūriki leaves Iwagakure weakened and demoralized. Ōnoki remains furious with Yechen but avoids launching a rash attack while his forces recover 182.
