In April 2026, Col. Ryan Bell's 3rd Mobile Brigade Combat Team, 101st Airborne Division, used the Infantry Squad Vehicle, a light tactical truck built to roll out of a C-17, as a mobile charging station for drones and soldier electronics at the Joint Readiness Training Center at Fort Polk, Louisiana. That experiment, modest as it sounds, is the clearest public signal yet that the Army is rethinking what a light tactical vehicle is for. Troops still ride in it. Increasingly, the more important cargo is kilowatt-hours.
The pressure starts with the kit soldiers now carry. Integrated Tactical Network radios, Enhanced Night Vision Goggle-Binoculars, and the proliferating small drones, including Short Range Reconnaissance quadcopters and Medium-Range Reconnaissance systems, all run on batteries that have to be recharged, often multiple times a day, far from any generator. As Bell framed it during the JRTC rotation, power generation has become one of the defining sustainment problems of the modern infantry company.
The service is responding on two parallel tracks. On the hardware side, Army research funding is supporting university work on foundational swarm-charging science for autonomous drone swarms — specifically, a cooperative agreement at the University of Illinois Chicago for autonomous swarm-charging science — which addresses the same power-generation gap Bell named at Fort Polk: a vehicle-mounted interface that can hand power to multiple aircraft at once, rather than trickle-charge one battery at a time.
On the acquisition side, the shift is more visible. Task & Purpose reports the Army is pursuing a heavier, hybrid-powered variant of the Infantry Squad Vehicle, a "Heavy ISV" explicitly framed as a "battery on wheels" to address the same power-generation gap Bell named. Jane's writes that new ISV variants are being positioned to "bring power to the battlefield," reframing the platform not as a mobility box but as a distributed mobile energy node.
That is a quiet inversion of how light tactical vehicles have been specified for decades. Procurement has usually optimized for payload, armor, and mobility, with power treated as a support function handled by larger trucks and generators. The ISV program, run by GM Defense, was sold as an airborne-deployable mobility platform first and foremost, which is exactly why fitting meaningful generation and storage onto it is hard. The original ISV was sized to fit inside a C-17 and to be sling-loaded under a helicopter. Add a heavy hybrid powertrain, export power, and a charging dock for drone batteries, and the airborne-deployable constraint is what gives.
A few honest limits apply. The DefenseOne excerpt cuts off in the middle of Bell's quote, so the specific cadence of charges per day, drone counts per vehicle, and any quantitative JRTC outcomes are not yet public. The Heavy ISV is a sought program, not a fielded one; nobody has yet rolled a hybrid ISV with a swarm-capable charging dock into a real rotation. And the 3rd MBCT trial itself was an improvised use of the existing ISV, with soldiers jury-rigging the power output rather than running it through an official charging interface.
What to watch next is narrow. The first signal will be whether the Army's university research on swarm-charging science moves from a cooperative agreement into a formal program and a designated platform. The second is whether the Heavy ISV solicitation, if it lands, ties its requirements to kilowatt-hours delivered per mission rather than to cargo capacity or armor level. If those numbers show up in the source selection, the sustainment shift Bell is gesturing at will have moved from experiment to specification.
