99. Blending: The Art of Hiding in Plain Sight with LtCol Erik Keim

[Editor’s Note:  Last week’s Mad Scientist Laboratory post featured an assessment by U.S. Army War College student LtCol Erik Keim (USMC) that “militaries will blend with civilian transmissions instead of relying solely on the specific military electromagnetic spectrum by 2030 due to the availability of Software Defined Radios (SDRs) and the proven success of digital camouflage.”
In today’s episode of The Convergence Podcast, Army Mad Scientist sits down with LtCol Keim to discuss the Future Dynamics of Warfare project he and his U.S. Army War College classmates collaborated on, his research on blending in the electromagnetic spectrum, and how the Army can adapt to the modern battlefield — Enjoy!]
LtCol Erik Keim is currently a resident student at the U.S. Army War College. He holds a Bachelor’s Degree in Computer Science from the University of Wyoming and a Master’s Degree in Information Technology Management from the Naval Postgraduate School. He is the recipient of the 2015 Rear Admiral Grace Murray Hopper Award from the Naval Postgraduate School. LtCol Keim is a Marine Corps Communications Officer with over 20 years of service and deployments to Iraq, Afghanistan, and throughout the Western Pacific.
In our latest episode of The Convergence podcast, Army Mad Scientist sat down with LtCol Keim to talk about his work on the Team Sullivan’s Travels project at the U.S. Army War College, what his research showed for the U.S. Army, and how blending might be a viable course of action on a cluttered battlefield. The following bullet points highlight key takeaways from our conversation:

Current military tactics use reserved frequencies and high-powered transmitters for communications. These actions stand out in the electromagnetic spectrum and make it easy for the enemy to triangulate and pinpoint the origin of the emissions for targeting and destruction.  


The on-going war in Ukrainehas shown that both sides are able to very quickly and easily identify and locate the source of communications transmissions and use a variety of kinetic attacks on those locations. Blending would be a viable alternative to using traditional military frequencies, with military communications “hiding within the noise” of commercial and civilian transmissions – e.g., WiFi, 4G and 5G, and Bluetooth. 


Blending in with the background electromagnetic spectrum “noise” makes it much harder for an adversary to detect and discern specific military communications from normal environmental transmissions.  This may come with added risk — Russia, for instance, transitioned to using cell phone communications but used unencrypted signals that Ukraine was able to intercept and act on. 


The contemporary battlefield shows that if you are operating anywhere in the world, you can be seen, and if you can be seen you can be hit.Military operations req
