Proudly show your support for the Eldian Scout Regiment by wearing a standard-issue cloak displaying the Wings of Freedom!

The Scout Regiment (調査兵団 Chōsa Heidan) 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."
