The Army is dusting off its tool kit and designing what it calls the “ISV-Heavy” — a tougher, battery-laden version of the Infantry Squad Vehicle that seems less like a war machine and more like a rolling power plant.

It’s the latest move in the Pentagon’s obsession with electrified equipment, a risky trend that may leave troops lugging lithium instead of lead on battlefields that demand grit, not gadgets.

While the average infantryman would prefer armor and firepower, the ISV-Heavy’s main mission isn’t to fight — it’s to generate electricity.

According to new contracting requirements, the vehicle will serve as a mobile generator that keeps drones, radios, computers, and even directed energy systems alive in the field.

Instead of armor plating, this “Heavy” rides into the next fight carrying circuits, cables, and batteries.

Jesse D. Tolleson Jr., principal deputy assistant secretary of the Army for acquisition, logistics, and technology, told senators last week that the new variant was designed specifically for “power generation at the mobile brigade combat team level.” In other words, the Army admits it doesn’t have enough juice for its high-tech toys.

The ISV-Heavy is meant to fill that “critical capability gap,” as Tolleson put it during a Senate budget hearing. Translated: it’s a battery truck.

The current concept reads like something straight out of Silicon Valley rather than the War Department.

The Army’s planning documents describe a vehicle capable of producing 60 kilowatts of continuous high-voltage DC power — the same output as a commercial charging station you’d find outside a big-box store. It’s supposed to keep up to 100 laptops running or power ten refrigerators in the field. Good news if the next war is fought at an EV dealership.

There’s also a “Sustained Silent Operations” mode, allowing it to run off a 60-kilowatt-hour battery with minimal noise, heat, or electromagnetic signature. Stealthy? Perhaps.

But soldiers still question whether this science-project-on-wheels can handle the brutal conditions of real combat. After all, it’s built on the same soft-skinned frame as the original ISV, which has struggled to live up to expectations.

The original Infantry Squad Vehicle, first fielded in 2019, quickly faced criticism. A 2021 Army report called the buggy “not operationally effective” for combat against a near-peer enemy — bureaucratic speak for “this thing won’t survive a firefight.” The Army’s solution wasn’t to make it tougher, but to change its mission.

By 2023, commanders officially redefined the ISV’s role away from direct combat, turning it into a glorified troop taxi meant to move quickly between objectives, not smash through them.

Now, with about 1,000 ISVs scattered among elite units like the 82nd Airborne, 101st Airborne, 25th Infantry Division, and the 75th Rangers, the Army seems intent on doubling down. The ISV-Heavy is supposed to complement its lighter sibling, giving infantry units a “mobile power node” as they operate in dispersed formations.

The Pentagon’s theory is that speed, mobility, and remote power will make American troops nimbler and deadlier. Reality says that surviving in modern warfare still takes hardened steel and overwhelming firepower.

Even so, the Army’s electrification experiment is spreading. National Guard units in Pennsylvania, Indiana, and Idaho are now transitioning from Strykers and Abrams tanks to lighter ISV configurations as part of the new Mobile Brigade Combat Team structure.

That’s quite the downgrade from 70-ton armor to an open-top “buggy” that would lose a bar fight with a roadside ditch.

Of course, real-world tests haven’t been in battle but in disaster zones. The 101st Airborne deployed over 100 ISVs in 2025 after Hurricane Helene hit the Southeast, navigating through debris and broken roads.

The vehicles proved handy for relief work, but relief efforts aren’t firefights. Using disaster recovery as a model for combat readiness might make sense in a conference room, not on a battlefield.

To its credit, the Army says General Motors has improved reliability issues since those early failures. It also commissioned three companies to deliver autonomous ISVs that could one day move troops and gear without a driver.

This tech-heavy direction might excite corporate contractors, but many veterans remember how the most complex projects tend to stall or break down when the shooting starts.

Army leaders claim their thinking comes from watching modern warfare unfold in Ukraine, where speed and small-unit agility have defined fights against drones, artillery, and missiles.

They may be right — but faster movement only matters when the gear that carries your troops can survive enemy fire. So far, the ISV is a long way from meeting that mark.

The deeper question isn’t just how much power a vehicle can generate, but whether the nation’s fighters are being equipped for power projection or power management.

Soldiers don’t win wars by charging phones. They win by having the strongest, most reliable tools of war at their fingertips.

If the ISV-Heavy is just another overcomplicated gadget to please Washington’s green-energy establishment, it may drain more than batteries when the next real war arrives.

The bottom line: while the War Department tinkers with electric grid experiments in camo paint, America’s infantry deserves machines built to endure the fight, not power the campsite. When push comes to shove, firepower beats voltage every time.
