U.S. Marines are testing a machine gun-wielding robot controlled by a tablet

By Luke Dormehl Published May 5, 2017

If there’s one thing we can probably all agree on it’s that it is a terrible idea to pick a fight with a robot tank equipped with a .50-caliber machine gun. That’s something that the U.S. Marine Corp is clearly hoping qualifies as a self-evident truth, based on its current testing of just such a vehicle for use in future battlefields.

Called the Multi-Utility Tactical Transport (MUTT), the vehicles are being developed by General Dynamics. They’re around the size of an ATV, and are available in four-wheeled, six-wheeled, or eight-wheeled tracked variations — providing a maximum of 1,200-pound payloads. The MUTT can function in one of two modes: either semi-autonomous, which means as a “controller-less small unit robotic follower,” or remote-controlled using a tablet or joystick.

However, the ambition is that over time they will evolve to be smarter in a way that will make them even more valuable for working alongside humans.

“Eventually, what we hope to do is go to systems that are more truly autonomous, that I can say, ‘Hey, go cover my right flank,’ and it’s going to go do the things it needs to do in order to make that happen,” a senior marine told Business Insider. “Then if it does get in the situation where the weapons systems malfunction, it can either fix itself, or then I’ve got to send a marine to go fix it.”

The versatile robots are primarily designed to transport food, water, and assorted other supplies, although the addition of a powerful machine gun opens up a variety of possibilities for engaging enemies or providing cover.

As with any area subject to automation, military applications require examination about exactly which tasks we’re happy to hand over to machines. No-one would suggest that a marine can be replaced by an ATV with a .50-caliber machine gun. But the advantages of a battlefield ally that doesn’t ever get fatigued, doesn’t need water, and can constantly support you with equipment in the field are also pretty clear.

Because some combination of the world’s best-trained military commandos and a gun-toting robot have to intimidate any possible opposition, right?

The Ioniq 5 is once again eligible for the $7,500 tax credit

2025 Hyundai Ioniq 5

After a brief and confusing absence, the Hyundai Ioniq 5 is once again eligible for the full $7,500 federal tax credit — and this time, it's sticking around (at least for now). So, what happened? Let’s unpack the ride.

The Ioniq 5, a sleek and tech-savvy electric crossover, initially made headlines not just for its design, but for being built at Hyundai’s brand-new Metaplant in Georgia. That domestic assembly qualified it for the EV tax credit under the Inflation Reduction Act (IRA), which requires vehicles to be made in North America with batteries sourced from trade-friendly countries. But early in 2025, the Ioniq 5 vanished from the list. Why? Likely due to its battery packs, which were then still being sourced from SK On’s Hungarian facility.

There are some spoilers ahead for the ending of Marvel's Thunderbolts. Stop reading now if you don't want to be spoiled.

Earlier this year, Captain America: Brave New World briefly introduced a new direction for James "Bucky" Barnes, a character Sebastian Stan has been playing since 2011 in Captain America: The First Avenger. In Brave New World, the former Winter Soldier apparently retired from being a reformed hero and went into politics by running for Congress. Thunderbolts reveals that Bucky won his election to the House of Representatives. But his stay in Congress was short.

Jeep Compass EV breaks cover—but will it come to the U.S.?

jeep compass ev us newjeepcompassfirsteditionhawaii 4

Jeep just pulled the wraps off the all-new Compass EV, and while it’s an exciting leap into the electric future, there's a catch—it might not make it to the U.S. anytime soon.
This is a brand new electric version of the Jeep Compass, and being built on Stellantis' STLA platform—the same architecture underpinning models like the Peugeot E-3008 and E-5008—it looks much slicker and packs a lot more inside than previous versions of the Compass.
Let’s start with what’s cool: the new Compass EV is packing up to 404 miles of range on a single charge, a 74 kWh battery, and fast-charging that gets you from 20% to 80% in about 30 minutes. Not bad for a compact SUV with Jeep's badge on the nose.
There are two versions: a front-wheel-drive model with 213 horsepower and a beefier all-wheel-drive version with 375 horsepower. That AWD setup isn’t just for looks—it can handle 20% inclines even without front traction, and comes with extra ground clearance and better off-road angles. In short, it’s still a Jeep.
The design's been refreshed too, and inside you’ll find the kind of tech and comfort you’d expect in a modern EV—sleek, smart, and ready for both city streets and dirt trails.
But here’s the thing: even though production starts soon in Italy, Jeep hasn’t said whether the Compass EV is coming to America. And the signs aren’t promising.
Plans to build it in Canada were recently put on hold, with production now delayed until at least early 2026. Some of that might have to do with possible U.S. tariffs on Canadian and Mexican vehicles—adding a layer of uncertainty to the whole rollout.
According to Kelley Blue Book, a Stellantis spokesperson confirmed that the company has “temporarily paused work on the next-generation Jeep Compass, including activities at” the Canadian plant that was originally meant to build the model. They added that Stellantis is “reassessing its product strategy in North America” to better match customer needs and demand for different powertrain options.
So while Europe and other markets are gearing up to get the Compass EV soon, American drivers might be left waiting—or miss out entirely.
That’s a shame, because on paper, this electric Jeep hits a lot of sweet spots. Let’s just hope it finds a way over here.
