Archive.org hosts a 93-page version of Hans von Dach’s seven-volume Total Resistance: Swiss Army Guide to Guerilla Warfare and Underground Operations. According to Wikipedia,
It was written in 1957 by the Swiss army officer Hans von Dach to prepare the Swiss population for an occupation of Switzerland by Warsaw Pact forces, an eventuality then considered possible in the context of the Cold War. The book has been republished as pirated translations in dozens of languages in numerous countries abroad, and notably found use by left-wing terror groups in the 1960s and 70s.
The version on Archive.org is a version published by Paladin Press, which went out of business in 2018 after the death of co-founder Peder Lund.
