The CIA isn’t known for sharing its secrets with anyone, let alone the public.  As such, the contents of an old Office of Strategic Services field manual aren’t something to be missed.

As SOFREP has covered previously, the days of the OSS were the glory days where espionage, sabotage, and war-fighting all converged under the banner of “Wild Bill” Donovan and the Allied fight against the Nazis during World War II, with resounding success.

The OSS, predecessor to the CIA, is often seen as the golden child of US intelligence operations, where innovative and unconventional organic solutions far outweighed the massive bureaucracy that plagues the US intelligence community today.

Enter the OSS’s timeless field manual for successful sabotage, which lists out various ways the OSS, Jedburghs, and Allies defeated their enemies: the Simple Sabotage Field Manual.

“Timeless Tips for Simple Sabotage”

As the CIA writes in their release of this field manual, “many of the sabotage instructions guide ordinary citizens, who may not have agreed with their country’s wartime policies towards the US, to destabilize their governments by taking disruptive actions.  Some of the instructions seem outdated; others remain surprisingly relevant. Together they are a reminder of how easily productivity and order can be undermined.”

The Simple Sabotage Field Manual covers a number of topics, namely tips and tools for motivating saboteurs, the tools, timing, and targets of sabotage, how to encourage destructiveness, and specific suggestions for success in your operational pursuits of sabotage.

Here is a list of five surprisingly “timeless tips”, as written by the CIA, that still apply to any enterprising saboteur today as well:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
