The Missing Power Layer of Modern Warfare

What It Covers

Adam Warmoth, founder of Chariot Defense, and Alex Miller, CTO of the US Army, examine the critical power infrastructure gap in modern warfare. Individual soldiers draw 30–60 watts continuously, distributed units require silent operation, and legacy diesel generators create targetable thermal and acoustic signatures that undermine every electronic system the army fields.

Key Questions Answered

• •Soldier power baseline: Individual soldiers today draw 30–60 watts continuously across radios, end-user devices, and drone batteries. Over a 72-hour operation, that equals 1.5–2 kilowatt-hours per soldier before accounting for squad, platoon, or command post loads. Planners must build power budgets starting at the individual level before scaling to unit requirements.
• •Signature management over raw output: A 15-kilowatt diesel generator running at 500 watts to meet peak demand creates a persistent thermal and acoustic signature that exposes position. Hybrid battery-generator systems eliminate this by running generation only at efficient load levels, then switching to silent battery mode, cutting detectable signatures without sacrificing operational capability.
• •Software-defined power routing: Plugging a coffee maker into a tactical command post can crash an air defense radar due to unmanaged load spikes. A software power management layer that staggers high-draw loads by 3-second intervals can reduce peak demand by a factor of three, directly cutting required system size and weight with zero operational impact.
• •Army acquisition restructuring: The US Army consolidated 13 program executive offices into 6 portfolio acquisition executives, each now controlling contracting, labs, and requirements generation under one authority. This structure enables portfolio-level trade-offs — accepting an 80% solution available in 30 days over a 100% solution requiring years of development — accelerating fielding timelines measurably.
• •Domestic battery supply chain strategy: China leads in battery cell production, creating supply chain risk down to soldiers buying Chinese-connected power banks at Home Depot. The Army and Department of Energy are directing roughly $500 million combined toward onshoring battery cell manufacturing. Defense companies can accelerate this by committing to purchase first production runs, helping suppliers descend the cost curve.
