Swiss military is a really interesting topic from so many perspectives. With such a high percentage of the population trained and involved in the military the terrain was also supposed to massively aid asymmetrical warfare. Holding mountain passes with light troops if need be.
There were even some books that were discussed to become regular army manuals and had to be vetoed by the chief of staff.
