Well, if Naruto leads an army in a fanfic, it could be a really exciting story. Naruto has a lot of experience from his own adventures. He'd be able to train his soldiers effectively, teaching them things like chakra control. His army could consist of various ninja from different villages who believe in his cause. They might go on missions to protect the ninja world from a new and powerful threat, and Naruto's ability to make friends and allies would be a huge asset in leading the army.
One scenario could be that a powerful and evil organization is trying to take over all the ninja villages. Naruto, being the hero he is, gathers an army. His army includes not only ninja from Konoha but also those from other villages who have heard of his reputation. They march towards the main base of the evil organization. Naruto uses his Sage Mode to sense the enemy's movements and positions. He divides his army into different squads for different tasks. Some are for frontal attacks, some for stealth operations. And in the end, with Naruto's leadership and the combined efforts of his army, they are able to defeat the evil organization and restore peace to the ninja world.
It could be about a character named Harry leading a group of retired army personnel in various adventures. Maybe they get involved in solving mysteries or facing threats that require their military skills and experience.
I'm not entirely sure as I haven't read that specific 'fanfic'. It could potentially be a story where Naruto has some sort of encounter with an army and there are killings involved in a fictional scenario created by the fanfic writer.
It could be an organization similar to the Akatsuki, but with a different goal. Instead of collecting tailed beasts, they are focused on conquering villages. Their army would be made up of powerful and diverse fighters, and Naruto would have to face their leader, who has some sort of special power or ability that makes them a formidable foe.
One main theme is leadership. Naruto has to step up and lead the newly - found army. He has to make decisions and inspire the members. Another theme is unity. The army, which may consist of different types of people or beings, has to come together and work as one. For example, if there are members from different villages in the army, they need to put aside their old rivalries.
Well, I'm not sure of the exact name, but there's a 'naruto finds an army' fanfic where Naruto finds an army of ancient warriors. These warriors were sealed away long ago and Naruto accidentally releases them. At first, they are hostile, but Naruto manages to convince them to help him fight against a common enemy. The fanfic is really interesting as it combines elements of Naruto's world with ancient legends.
In the fanfic, Naruto might destroy the army in a very unique way. Instead of using his typical Rasengan or Shadow Clone Jutsu, he could discover a new power within himself. Maybe he unlocks a special form of Sage Mode that gives him the ability to control the elements in a completely different way, allowing him to take on the army with ease.
One possible plotline could be Naruto being transported to the Army of Two world and having to learn how to work with the partners in that world. He could use his ninja skills to help them in their missions.
Well, he might be initially confused. Naruto comes from a world with ninjas, not a modern army base. He could think it's some new kind of enemy stronghold. Maybe he'd try to infiltrate it in his typical ninja way, using stealth and jutsus.
