The U.S. Army just proved that it doesn't always need a long runway or a massive cargo plane to move a motorized infantry squad. During a training exercise at Marine Corps Base Hawaii on March 29, 2026, a single CH-47 Chinook helicopter lifted two Infantry Squad Vehicles (ISVs) simultaneously. It's a move that looks cool for the cameras, sure, but it actually signals a massive shift in how light infantry will fight in the Pacific.
If you're wondering why this matters, look at a map of the Indo-Pacific. It's thousands of miles of water and small islands. Roads are a luxury. If a commander can drop nine-man squads with their own sets of wheels directly onto a beach or a jungle clearing, that commander wins. Using one helicopter to do the work of two isn't just about saving fuel; it's about speed. In modern warfare, the slower you are, the easier you're hit.
The Math Behind the Lift
The CH-47F Chinook is a beast, but even beasts have limits. To understand how it can carry two trucks at once, you have to look at the weight. Each GM Defense ISV weighs around 5,000 pounds when empty. The Chinook’s tandem sling load capacity sits at roughly 25,000 pounds. You do the math. Even with gear, two ISVs are well within the margin.
What's impressive here isn't the weight itself—it's the stability. Sling-loading one vehicle is tricky. Sling-loading two creates a complex aerodynamic puzzle. If those vehicles start swinging like a pendulum, they can take the helicopter down with them. The soldiers from Alpha Company, 2nd Battalion, 27th Infantry Regiment ("Hellraisers") had to prep these vehicles perfectly. Every strap has to be tight, and every piece of loose gear has to be cleared.
Why the ISV is a Different Kind of Military Truck
Most military vehicles are heavy. The Humvee is a pig. The JLTV is even heavier. They're built to survive roadside bombs, which is great for Iraq but terrible for a helicopter. The ISV took a different path. GM Defense basically took a Chevy Colorado ZR2 chassis and stripped away everything that wasn't essential.
- 90% Commercial Parts: It uses a 2.8L Duramax turbo-diesel engine you can find in civilian trucks.
- Weight: Keeping it under 5,000 pounds was the "North Star" of the design.
- Seating: It fits nine soldiers—exactly one squad.
By ditching heavy armor, the Army prioritized "mobility as protection." The idea is that you're harder to hit if you're moving 60 mph through the woods than if you're crawling along a road in a 15-ton armored box.
Strategic Reach in Operation Pathways 2026
This Hawaii lift wasn't just for show. It’s a warm-up for Operation Pathways 2026. This is the Army's big push to prove they can operate in the "first island chain" near China. When the 25th Infantry Division practices these lifts, they're practicing for a scenario where a pier is blown up or a runway is cratered.
Traditionally, if you wanted to move vehicles, you needed a ship or a C-17. Both are huge targets. A Chinook can fly low, hide in the terrain, and drop these vehicles in a "cold" landing zone. Because the ISV is so light, the helicopter doesn't even have to land. It can hover, drop the load, and disappear in seconds.
Real World Limitations and Risks
I've seen enough of these tests to know they aren't foolproof. There’s a reason why you don't see two ISVs hanging under every Chinook flight.
- Pilot Workload: Flying with a dual sling load is exhausting. The pilot has to manage the "feel" of two separate masses reacting to the wind.
- Fuel Consumption: Drag is the enemy. Two boxy trucks hanging in the wind create a massive amount of air resistance, which eats into the helicopter's range.
- Vulnerability: While the helicopter is fast, a sling load makes it a bigger target. You can't exactly pull evasive maneuvers with 10,000 pounds of steel swinging beneath you.
Your Next Steps
If you're following military tech or logistics, keep your eyes on the upcoming exercises in the Philippines and Japan. The "two-truck, one-bird" concept is likely to become the standard for the 11th Airborne and 25th Infantry Divisions.
If you're a civilian enthusiast, don't expect to buy an ISV at a dealership anytime soon, but you can see its "DNA" in the Colorado ZR2. For the Army, the next hurdle isn't just lifting the trucks—it's figuring out how to keep them fueled and repaired when they're 500 miles away from the nearest base.
Watch the footage from the Hawaii exercise if you get a chance. Seeing that tandem lift in person reminds you that sometimes, the simplest solutions—like a very strong rope and a very big engine—are the most effective.
