Allied Shinobi Forces' Headquarters

When the Allied Shinobi Forces was formed, its headquarters was designated to be in the vicinity of Kumogakure for ease of command over the course of the Fourth Shinobi World War. Originally, members of the Five Kage, including Tsunade, Ōnoki, and A, due to the fact that he was the Supreme Commander of the Alliance, were stationed there to help with command decisions and battle plans.

Both the Intelligence Division and Sensor Division were stationed in the headquarters so that they could give crucial intelligence and sensor reports to the various divisions through the Sensing Water Sphere that Inoichi Yamanaka and Ao had created.  The Alliance's Chief Strategist, Shikaku Nara, was also stationed at the headquarters, where he came up with plans to counter Kinkaku and Ginkaku, as well as Asuma Sarutobi and the White Zetsu Army's threat. In the latter stages of the War, after the remaining Kage gathered to fight the reincarnated Madara Uchiha, Shikaku was left in command. When it came to fight the Ten-Tails itself, Shikaku commanded each part of the army seamlessly, immobilising the Ten-Tails' initial form and leaving the freshly unmasked Obito Uchiha as well as his partner, Madara, vulnerable to counter attack. Ultimately though, when the Ten-Tails reached its second form, the headquarters was wiped out by its massively powerful and long ranged Tailed Beast Ball, but not before transmitting Shikaku's final strategy to the Alliance.
