The Marines wrote it down
Last week the Marine Corps published its vision for the ground combat element through 2040. It expects squad-level drone defenses, troops who carry loitering munitions, autonomous robots, and tools for Marines to assess their own electromagnetic emissions so the enemy cannot find them first. Lt. Gen. Jay Bargeron called low-echelon defense against one-way attack drones one of the biggest holes the service has.
The hardware is already moving. The Corps fielded its first 80 sets of a man-portable counter-drone system this summer. Infantry squads are back to 13 Marines, one of them a dedicated drone operator. The service planned to get 10,000 small drones into infantry battalions, reconnaissance units, and littoral teams by the end of the year.
Each new capability adds a signature
A squad with a drone, a counter-drone kit, a phone per Marine, and a radio is a squad with several transmitters. The drone's video downlink, the controller's command link, the phones syncing their maps, and the radio net all radiate. Ukraine has spent three years showing what happens to emitters: they get found, and then they get hit.
Bargeron's point about dispersion cuts both ways. Spreading technology into the smallest units makes them harder to find only if the technology is quiet. A dispersed squad that streams video back to a command post all day has made itself easy to locate.
Process locally, send the result
The most effective emissions control is to transmit less, and the way to transmit less is to do the work where the data is collected. A camera that detects a vehicle on the device and sends a typed detection uses a tiny fraction of the airtime of a camera that streams frames to a server. A radio transcript is a few lines of text. A position update sent only when something moves costs less than a fixed-rate beacon.
EdgeLance is built this way. Detection, tracking, transcription, and the mission AI run on the hardware the squad already carries, and what crosses the mesh is the result: a detection, a track, a task, a line of transcript. Full video clips stay on the device until someone asks for them. We covered the bandwidth side of this in the sensor fabric post. The emissions side is the same design with higher stakes.
Make the emissions visible
The Marines want tools to assess their own signature. Part of that is RF measurement, which EdgeLance's RF capability supports alongside emitter detection of the other side. The other part is knowing what your own software is about to send. Every message EdgeLance syncs is a typed record with a size and a priority, so a unit can see what its nodes are sending, set budgets by phase, and hold low-priority traffic during a quiet period without losing it.
The 2040 document calls itself human-centric. A human-centric squad of 13 should not have to think about how much its software is transmitting. The software should already be quiet. We made the same argument about spectrum denial and cloud AI in March.
