Legion Sergeants are PFC members who were promoted to lead squads and platoons. The Sergeants are essentially the commanders of the PFC's and Ghosts within games.
Generals are similar to Sergeants, but on a larger scale. Generals and Legion Major Generals are given a very large variety of permissions within the discord and ingame, and can be given specific jobs by the Legion Commander or 2iC, rather than having one specific job within the legion. There are two types of Generals, normal Legion Generals, and Legion Major Generals.
