Elves were actually quite familiar with militia organizations like the "People's Assault Team," because they were the first to establish such an organization—the so-called "National Assault Team."
Before Li Lin appeared, when the elf clan was still living in villages and tribes, they were a race where everyone was a soldier. In an extreme environment where powerful enemies lurked and one false move could lead to the annihilation of their race, achieving this level of mobilization was the only way to survive. Later on, as the doctrine of total war became the core military thought of the Wehrmacht, the concept of the "National Assault Team" emerged. Its main purpose was to establish a citizen armed forces of guerrilla nature, while also serving to train reserve personnel. Generally speaking, it was still a type of militia organization. It had a lot of similarities with Charlemagne's "People's Assault Team."
