Have you ever imagined your favorite off-roading truck designed to withstand the rigors of combat? That is really the story behind GM Defense's ISV and IUV, two light military vehicles featuring over 90% of the parts from the Chevy Colorado ZR2.
Once only a supplier for the U.S. Army, Canada and NATO countries are adopting these tactical trucks. Why? Because they are rapid, light, serviceable—and most importantly, they are familiar. It is as if sending soldiers into the field with the knowledge of how to fix their own equipment.
Built for Combat, Powered Like a Chevy
Both vehicles are powered by the 2.8-liter Duramax turbo-diesel engine, the same engine that Chevy fans know all too well from the Colorado, and this is by design. GM did not want dependability issues or logistical hindrances, especially when operating in a combat zone far from a main base.
- Less down time: With easy accessibility to parts, damaged components can be changed over quickly.
- Mechanic friendly: Soldiers and field engineers do not require any special training to repair familiar equipment.
- Proven reliability: These engines have more than just countless civilian miles, they are combat tested.
Why Lightweight Makes the ISV a Big Deal
These will most likely never see the tank move. The ISV (Infantry Squad Vehicle) can carry nine soldiers over rugged terrain quickly, while the IUV (Infantry Utility Vehicle) version can carry loads.
The neat parts are they can be:
- Flown in a C-130 or A400M
- Airlifted in a helicopter like Blackhawk or Chinook
- Dropped in place and ready to go.
This makes the ISV an excellent option for rapid deployment, humanitarian missions, and quick reaction forces that should move fast without the burden of heavy armor.
Real People. Real Missions. Real Value.
It’s a story about practicality over flash, the hardware is secondary. Troops on the ground have touted the comfort, speed, and reliability of the ISV.
“It’s like driving a bigger, beefier Chevy, through the desert,” said one soldier quoting a military publication.
Here’s why soldiers and decision makers love these machines:
- Familiar controls: it feels like a civilian truck inside
- Cost per unit: uses COTS parts so there’s no custom build rate
- Mission Kits: you can add stretchers, weapons mounts, communications gear etc.
These trucks prove you don't need heavy armor to prepare for modern warfare - you need agility, adaptability, and the power of smart engineering over building bricks.
Already Serving Across Borders
GM Defense didn't just build these for the U.S. Army. Canada has ordered them already and NATO allies are testing them now. Whether for military patrols, logistics, or emergency response, these vehicles have a light footprint and are off-road-worthy.
In the military of today, there are so many different areas of operation that the emphasis has shifted from brute force to speed, technology, and flexibility. The ISV and IUV are great examples of where military capability is headed.

Conclusion
GM Defense is demonstrating through its ISV and IUV how clever engineering can repurpose a civilian truck into a mission-ready military vehicle. By using mostly Chevy Colorado parts - of which there are plenty and are affordable and reliable - GM is able to achieve a vehicle that is confident in fast-moving operations. The increasing popularity of the ISV and IUV in the U.S. military, Canada, and NATO, demonstrates that modern militaries are just as interested in being agile and practical as they are about overwhelming their enemy. Whether that is quickly handing troops a way to get to the front line or provide humanitarian relief after a disaster - these trucks are showing that sometimes the best military technology comes straight from our driveway.
