SOME THOUGHTS ON COMSEC & THE GUERRILLA, FROM THE RADIO RECON GROUP TELEGRAM CHANNEL
Some food for thought regarding COMSEC at the tactical level:
Based on what we know from UKR, the emphasis on SIGINT at the small unit level has become the top priority. Coming out of this war, regardless of outcome, will confirm a concept US Army SOF piloted and the USMC would later adopt with the Radio Recon Platoons – pairing a SIGINT asset with an advanced marksmanship asset for targeting in real time.
With regard to SIGINT, the targeting had been focused on two mutually exclusive tools: drones and the radios being implemented for fire and maneuver. That said both sides have relied upon digital waveforms (UKR/DMR, RUS/NXDN), both of which are easily targeted via direction finding.
UKR is a symmetric fight. This point is lost among many caught up in the drama of being contemporary. Such thinking does not in any way benefit the Guerrilla. Knowing that ground SIGINT assets will be trained primarily to target digital waveforms, remaining analog has a big value. Something as simple as a voice scrambler obscures your transmission just enough to conceal the message contents while remaining analog on a spectrometer (like the TinySA). It could very well cause an enemy to dismiss your traffic altogether, since it appears unsophisticated.
Not in any way saying this is an absolute, but it is however an idea thinking forward.
