In 1944, the Office of Strategic Services — the predecessor of the post-war CIA — was concerned with sabotage directed against enemies of the US military. Among their ephemera, declassified and published today by the CIA, is a fascinating document called the Simple Sabotage Field Manual (PDF). It’s not just about blowing things up; a lot of its tips are concerned with how sympathizers with the allied cause can impair enemy material production and morale:
- Managers and Supervisors: To lower morale and production, be pleasant to inefficient workers; give them undeserved promotions. Discriminate against efficient workers; complain unjustly about their work.
- Employees: Work slowly. Think of ways to increase the number of movements needed to do your job: use a light hammer instead of a heavy one; try to make a small wrench do instead of a big one.
- Organizations and Conferences: When possible, refer all matters to committees, for “further study and consideration.” Attempt to make the committees as large and bureaucratic as possible. Hold conferences when there is more critical work to be done.
- Telephone: At office, hotel and local telephone switchboards, delay putting calls through, give out wrong numbers, cut people off “accidentally,” or forget to disconnect them so that the line cannot be used again.
- Transportation: Make train travel as inconvenient as possible for enemy personnel. Issue two tickets for the same seat on a train in order to set up an “interesting” argument.
