Allied Shinobi Forces

The Shinobi/Samurai Alliance is a coalition between the collective military might of the Hidden Village of the Shinobi nations of the Lands of Lightning, Water, Earth and Wind, and the lone Samurai nation of the Land of Iron. The purpose of this alliance is to stand up together against the threat of the Akatsuki organization and the tailed beasts, in the Fourth Great Shinobi World War. Because of the deceitful actions of the Sixth Hokage, they intend to ask Kakashi Hatake about the Land of Fire's Hidden Village of Konohagakure's entrance into the alliance.

The coalition was formed after Madara Uchiha's declaration of war after the Kage refused to hand over Killer Bee and Naruto Uzumaki, the jinchuriki of the Eight-Tailed Giant Ox and the Nine-Tailed Demon Fox respectively. When Madara departed, the Kages and Mifune discuss their plans on dealing with Madara and the tailed beasts.

Purpose
The purpose of the coalition is primarily to defend the jinchuriki from Madara. The jinchuriki, once caught will complete Madara's Eye of the Moon Plan. Therefore, the coalition plans to first find the two jinchuriki before Akatsuki and keep them safe, away from the battlefield if necessary. Beyond that, their duty is to put a united front against Akatsuki's seven tailed beasts.
