American Partisan: SIGINT for Everyone

NC Scout at American Partisan has an informative article up, Signals Intelligence: Capabilities for Anyone, discussing readily available and simple equipment that anyone can use to build their signals intelligence capabilities. Signals intelligence is one of the best, if not the best, ways to know what is going on around you, whether that is in the aftermath of a disaster or during a civil disturbance/conflict.

One of the points I’ve stressed for a long time is the value found in using simple equipment to the maximum of its potential. Whatever it might be optics to weapons to electronics, my own combat experience has fostered an appreciation for Keeping it Simple, Stupid. And that’s the very paradigm I teach my class from–taking what’s common and simple to understand and learning the techniques of using it to its peak potential. The same is true for building signals intelligence capabilities among preppers and/or potential partisans. Not that long ago the RAND Corporation published a white paper on the very topic; what they found was that not only does the capability exist to monitor most real-world threats in any given environment, anyone can do it.

During our market scan, we found examples of SIGINT capabilities outside of government that are available to anyone. The capabilities we found have applications in maritime domain awareness; radio frequency (RF) spectrum mapping; eavesdropping, jamming, and hijacking of satellite communications; and cyber surveillance. Most of these capabilities are commercially available, many are free, and some are illegal. In our view, the existence of both legal and illegal markets and capabilities results in an environment where SIGINT has been democratized, or available to anyone.

From experience monitoring the Taliban on a decade old Radio Shack Pro-96 in Afghanistan, an undisciplined adversary will usually tell you everything you want to know over the air. Even if he thinks he’s secure with electronic encryption, the presence of the signal itself can be detected as soon as he keys up. After working with several private groups and teaching techniques to not get found in my RTO Course, I can positively say that a lot of people are at a distinct disadvantage in the communications department not through equipment but through a complete misunderstanding of the actual function of their gear. As anyone who’s trained with me knows, tactical communications is a whole other animal from nearly everything folks think they know. The first rule of Signals Counterintelligence is to have a competent plan and not set patterns. But what about collection? Those same mistakes we aim to correct through training are likely to be repeated by the opposing force. Even if they have all the technical enables in the world, a lot can be done with basic equipment…
