"The First, Third, and Fifth Divisions will fight on the front lines, while the remaining Second and Fourth Divisions will provide support and cover one another!"
"With that, the overall formation of the Allied Shinobi Forces is complete."
Shikaku Nara pointed at the map, showing the assembled leaders in the conference room the formation he had assigned to the Allied Shinobi Forces.
"Well arranged. Let's proceed with that." Shihōin Naraku was the first to nod his approval. "Whatever the enemy plans, they only have these three attack routes. Shikaku and the members of the Staff Department have already considered every issue."
With their lair in the Mountain Graveyard, the enemy could only attack the Land of Fire from due north, the east, or the west. Simply put, they had three marching routes: the front, the left, and the right.
Of course, if they wanted to take a longer detour, the White Zetsu army could use their unique ability to travel underground to circle around behind the Allied Shinobi Forces and attack from the south of the Land of Fire.
But that would be rather counterproductive.
For one thing, it would be useless. After all, even underground, a large-scale march would be difficult to hide from the Allied Shinobi Forces' Intelligence Department.
A small force might be able to travel undetected.
But the White Zetsu army numbered in the thousands or tens of thousands. Movement on that scale simply could not be concealed.
Ninja had all sorts of detection methods, which were very difficult to guard against.
Detection using only chakra and ninjutsu was relatively commonplace, but searches and reconnaissance using flowers, birds, fish, and insects were not so easy to evade.
So as long as Obito Uchiha had any sense, he would not choose to circle all the way around
