Surprise Attack Division

The of the Allied Shinobi Forces is a group of shinobi that were placed together as a battalion because of their skills at ambush attacks.

Ambush Division vs. Ambush Division
After their formation and brief introduction to each other, the squad mobilizes via Sai's ink birds in order to advance into the enemies territory from the air. During this aerial journey, Omoi's anxiety soon develops into a deep concern that doesn't go unnoticed by his captain. When questioned whether he himself is worried, Kankurō retorts that considering how crucial their mission is in determining the extent of future causalities, their thoughts should be solely focused upon making the operation a success.

After landing in the densely forested terrain, Kankurō quickly details the priorities of their main assignment, which includes the construction of various bases and the establishment of numerous covert traps. Proceeding with the assembly of the main base, he then orders Omoi to place traps around the perimeter, before telling Sai to return to the air and continue with observation, while Ittan excavates trenches utilizing his earth release techniques. Tango is then assigned to the construction of the chakra transmission antenna, as Zaji and Hoheto survey the immediate area with their respective sensor-type abilities, allowing Kankurō and Kiri to formulate the battle strategy.

However; just moments after completing these ordained tasks, Zaji detects the injured Muta Aburame and quickly attempts to help him, impetuously charging beyond the perimeter. Thanks to Hoheto's Byakugan, Muta's arrival is swiftly exposed as a devious trap, orchestrated by Akatsuki's Surprise Attack and Diversion Platoon from afar and despite a substantial explosion Kankurō manages to successfully retrieve and save Zaji. Simultaneously to this Ittan, using another of his earth techniques, rescues the entire division by plunging the surrounding terrain deep into the ground. Unfortunately these actions are unable to save Muta but before they even have time to mourn, they are assaulted by two other members of the defeated Infiltration and Reconnaissance Party, both of whom are now under Sasori's control. These aggressors are warded off thanks to Omoi's proficient sword skills, but yet again they are attacked from above, this time by Shin, who is in turn repelled by Sai. Evidently shocked by the appearance of his deceased 'brother', Sai is momentarily unable to reply, leaving Omoi to instead raise his blade with the determination of defeating these present foes.

Seemingly launching into an unequivocal charge towards a nonchalant Deidara, Omoi instead conducts a graceful yet deceptive maneuver in order to sever Sasori's ties with the incapacitated victims, allowing Hoheto and Tango to recover their exhausted forms. Exploiting this momentary opportunity, Kankurō dexterously attaches his own respective chakra threads to those belonging to Sasori, before utilizing a forceful pull to bring his adversary down to the rapidly rising earth below, in turn crushing a sufficiently disorientated Deidara. Kankurō then ignores his opponent's subsequent compliment, remarking instead that his Black Secret Technique has now surpassed those of the master of the Red Secret Technique, just as he summons Sasori's former 'body'. Ordering Ittan to fabricate a protective barrier around the injured while Kiri focuses upon their treatment, Kankurō is alerted by Hoheto to the presence of a quantity of exploding clay within Shin's stomach but after the announcement that the ability can be deactivated by lightning based techniques, Omoi admits that he possesses a few.

Sortieing once again, Kankurō and Omoi ineffectually clash with a manipulated Shin, only to lure him into a previously concealed trap just moments before Deidara is able to activate the consumed volatile substance. Hearing the resultant explosion reverberate through the confines of the dense dome, Zaji informs Kiri that those outside are still alive, despite some seemingly incurring minor injuries. A slowly awakening Sai, evidently angered by Deidara's proceeding referral to the rapidly reforming Shin as simply "the bomb", recovers the remainder of his scattered belongings, before defiantly challenging his current opponents with a fully saturated brush in hand. Appearing suddenly behind the dumbfounded foes, Sai's Benevolent Kings propel the pair straight into the clutches of Kankurō's puppets, where he uses a combination of his own Black Secret Technique: Machine Triple Shot and Omoi's lightning chakra infused blade to seal them inside. Commending Omoi on a job well done, Kankurō assures him that his technique will be enough and so he should instead provide assistance to the others, but by this point Shin's soul had already begun to depart, freed from its bonds after observing Sai's drawing of the 'brothers'.

Kankurō then uses the coil of Sasori's puppet body to make sure the Black Ant puppets will remain closed. He then tells Sasori that his strength came from his soul not in spite of it and that the way he should have been immortalized was through the puppets he'd leave behind that he put is heart and soul into making. He then says that he should have been a top class puppeteer not someone that allows someone else to manipulate him, and that one's soul forever remains in his creations. Sasori acknowledges Kankurō's words and as his soul begins to return to rest, he calls out to Kankurō, entrusting his Mother and Father puppets to him, and leaving him with instructions to pass them on to the next generation. As Sasori's form reverts to dust and ash, Kankurō explains that it looks like their enemy's technique has a hole in it, pointing out that people's inner emotions aren't so easy to restrain. He then orders him his team to prepare to launch their ambush.

The War Begins
Encountering a modest yet elite cell from Akatsuki (consisting of Haku, Zabuza Momochi, Gari of Iwagakure and Pakura of Sunagakure), the Surprise Attack Division make their first actual assault against the opposition's main forces. Utilizing numerous exploding tag's attached to artificial birds, the squad effectively catches the adversaries unaware but thanks to their respective immortality, the enormous blast is rendered ineffective. Observing this futile conclusion, Zaji lights a distinctive red flare while Sai continues the barrage, indicating that they require immediate assistance. As the temperature of the surrounding atmosphere undergoes a drastic decline, Haku appears from above and causes the squad to painfully fall to the ground below, where the remainder of their foes immediately charge the company. Arriving just in time to intercept the attack, the Third Division assumes the principal role in the confrontation, while the Surprise Attack Division provides support.

Concluding their part in what is now the Third Division's conflict, Kankurō accompanied by Hoheto, Ittan and Kiri, return to the destination of their previous battle in order to attend to the captured Deidara. However, upon arrival they unfortunately congregate with further opposition, this time comprised from Chiyo, Chūkichi, Kimimaro and Hanzō. In spite of Chiyo's complementary comments and Hanzō's derogatory ones, Kankurō retains his composure and promptly orders the rest of his squad to await his signal to retreat.
