The Shiganshina District is a town located on the south edge of Wall Maria which is located on the island of paradise and is the hometown of Eren Yeager, and his bestfriends Armin Arlert, and Mikasa Ackerman. The district is built within an outcrop of Wall Maria. Since Shiganshina is located to the south, Titans usually came to this district's Walls in an attempt to consume humans, but were only able to break through in the year 845 because of the 60-meter tall Colossus Titan.
The Scout Regiment is the branch of the Eldian military most actively involved in direct Titan combat, Titan study, human expansion, and outside exploration. Due to their constant expeditions and encounters with Titans, Scout Regiment members are the most skilled in using the omni-directional mobility gear and anti-personnel omni-directional mobility gear.Despite having little success before 850, they still symbolized "the hope of mankind" with their insignia being known as the "Wings of Freedom." By 851, thanks to the actions of the Scout Regiment, Wall Maria had been completely resettled. By 854, the Scout Regiment had become the Eldian military's main expeditionary force, engaged in open warfare against the nation of Marley.
The scout regiments adventures that take them beyond the walls are treacherous but yeat they still push forward because that's the only way to survive.
