Heavy Machinery Sabotage (May 2026)

We are writing this zine as anarchists living in so-called Canada seeking to spread attack against extractive projects of the state and capitalism. We come from an insurrectionary, eco-anarchist, anti-extractivist, and anti-colonial background, and draw inspiration from the methods and tactics employed by eco-saboteurs in the ecological movement in North America through the 1990s and early 2000s. Building off of various monkeywrenching techniques from this era, this zine will focus on updating information around tactics and techniques of sabotage against heavy machinery. ...

A Practical Security Handbook: No Trace Project edition

PDF: read | letter booklet part 1 , part 2 | tabloid booklet • TXT Note from the No Trace Project: A Practical Security Handbook for Activists and Campaigns was originally published in the United Kingdom in 2004. While part of this handbook is now outdated, we believe some of it is still very relevant. This document is a partial re-edition of the original handbook. We have freely adapted its contents, leaving out sections that we deemed outdated or irrelevant to this re-edition, improving wording, and changing a few details, while trying to stay as close as possible to the spirit of the original text. We have also added footnotes to point the reader to up-to-date information on DNA, CCTV, and other topics. ...

How to defend yourself during a police interrogation

PDF Preface to the English version In summer 2022, 2000 copies of this book were printed in French and 2000 in German . The french version is now sold out, and the Publisher « Éditions du Commun » had now reissued the book. The book was written with the intention of serving as a tool of self-defense against the manipulative interrogation strategies employed by the police. As stated in the introduction, “ It addresses readers in various countries in which legislation may differ“. And indeed, we soon received feedback that the content conveyed by the book is equally applicable to countries such as Turkey, Morocco, Serbia, Italy, Denmark, and many more. And soon a number of supportive people were offering to translate the book into other languages. This is what happened with the English version, and we’d like to take this opportunity to warmly thank our translator and proofreader for their fine work. ...

How to Form an Affinity Group

The Essential Building Block of Anarchist Organization Turbulent times are upon us. Already, blockades , demonstrations , riots , and clashes are occuring regularly. It’s past time to be organizing for the upheavals that are on the way. But getting organized doesn’t mean joining a pre-existing institution and taking orders. It shouldn’t mean forfeiting your agency and intelligence to become a cog in a machine. From an anarchist perspective, organizational structure should maximize both freedom and voluntary coordination at every level of scale, from the smallest group up to society as a whole. ...

Flyer: When the Police Attack

The police are in our way. They are in the way of the demo continuing: to the next block, the bank windows downtown, the police station and government offices. They are also blocking our way towards something else: towards a world without bosses, cops, and prisons, as the good old slogan says. But before being in our way, they are first and above all… the police, an institution based on colonization, racism, and the state’s monopoly on violence. We will have no other choice but to confront them as an adversary in each of our struggles. ...

A recipe for nocturnal direct actions!

[ For reading ] [ For printing, 11”x17” ] “Direct action, simply put, means cutting out the middleman: solving problems yourself rather than petitioning the authorities or relying on external institutions. Any action that sidesteps regulations and representation to accomplish goals directly is direct action—it includes everything from blockading airports to helping refugees escape to safety and organizing programs to liberate your community from reliance on capitalism .” ...
