Sasuke Recovery Team

The Sasuke Retrieval Team is an emergency-response team formed because of Sasuke Uchiha's defection from Konohagakure to Otogakure. Because of the A-rank nature of the mission, the retrieval team would ordinarily have been composed of chūnin and jōnin. However, because Konoha is still suffering from a loss in manpower due to the invasion of Konoha, the Fifth Hokage can send only minimal forces. She hands leadership of the squad to Shikamaru Nara - making it his first mission since being promoted to chūnin - and allows him to recruit as many genin as he would like. The team's mission is the basis for the Sasuke Retrieval arc.

The formation for pursuing Sasuke and his escorts, the Sound Four, was designed by Shikamaru to be able to react to an enemy attack as quickly as possible. The members were lined with this order:
 * 1) Kiba and Akamaru, who would lead the group, track Sasuke's scent and check out the enemies' scent to evade booby traps as they have the most familiarity with the Land of Fire's terrain. Kiba had to be looking straight ahead. With the help of Akamaru, Kiba would be good to watch up front if an enemy did a frontal attack.
 * 2) Shikamaru, who would be able to give orders quickly based on how any situation encountered by Kiba unfolded. Shikamaru had to look ahead too, but with a wider range than Kiba and Akamaru.
 * 3) Naruto, who has quick reactions and the Shadow Clone Technique to aid the front or the rear in an emergency. Naruto had to be watching left.
 * 4) Chōji, being the bulkiest in the group, would be the final blow after a surprise attack. Chōji had to be watching right.
 * 5) Neji, who would take care of the rear thanks to the Byakugan. Neji would be watching the back and taking care of any blind spots in the formation.

The squad pursued the Sound Four and Sasuke for some time, growing smaller as its members broke up into one-on-one fights with the Sound Four and then their fifth member, Kimimaro. Chōji and Neji both ended up near death after defeating their opponents, Jirōbō and Kidōmaru. Kiba and Akamaru were nearly killed by Sakon and Ukon, but were saved by the timely intervention of Kankurō. This situation was repeated with Shikamaru being saved by Temari from Tayuya. Naruto engaged Kimimaro in battle for a while but was not a match for him. Rock Lee saved him in order for him to continue pursuing Sasuke. Gaara, in turn, saved Rock Lee, and both were then saved by Kimimaro's succumbing to disease. When Naruto faced off with Sasuke the battle ended in Sasuke's favour, but he chose not kill Naruto. In the end, the mission was a failure, as Sasuke successfully joined up with Orochimaru.
