Don't know if that's true with the Rangers. While they ARE considered to be Special Forces, Ranger training is taken by a lot of Army personnel, officers in particular, that never join a Ranger battalion. Just look at all those Ranger Tabs worn by senior field grade & general officers. If every one of those guys had actually commanded or did staff time with the Rangers, it wouldn't have been the 75th Ranger Regiment -- rather it would have been the 75th Ranger DIVISION.
