Chariot Defense’s M424 tackles the Army’s 30–60-watt soldier power burden and generator signatures
Modern warfare is becoming more distributed, electronic, and vulnerable to detection, yet soldiers still depend on inefficient diesel generators and lead-acid batteries. Alex Miller, CTO of the U.S. Army, says an average soldier continuously draws 30–60 watts—up to 2 kWh over 72 hours—before adding drones, radios, and command systems. Chariot Defense CEO Adam Warmoth describes the M424, a 4 kW hybrid power system with 4 kWh of storage that ran radios, electronic warfare equipment, and drones for 36 hours without detectable thermal or acoustic output. Its software layer buffers surges, manages voltage and frequency, and lets generators shut down for low-signature operations. The Army’s Transforming in Contact initiative put Chariot’s system into the field within six months, illustrating a procurement shift toward rapid experimentation, commercial technology, and outcome-focused acquisition. Officials also outlined nearly $300 million in battery-cell investments to rebuild U.S. supply chains.
