Colombia Arms DJI Matrice 300 Drones With Grenades

Colombia just acquired 3,744 grenades built to fall from drones, and the aircraft doing the dropping are off-the-shelf DJI Matrice 300 RTK quadcopters. The grenades are homemade by the state arms maker Indumil, and they’re already in service with the Army’s drone battalion. It’s the clearest sign yet of where Colombia’s long fight against armed groups is going: a commercial Chinese drone, a domestic warhead, and precision from the air.

What Colombia Actually Bought

The Colombian National Army has taken delivery of 3,744 GADCI aerial grenades, along with an unspecified number of the SLAGA launchers that carry them. Both are made by Indumil, the country’s state-owned arms manufacturer, which means the munition itself is domestic, not an import.

The grenades are already in operational service. They’ve been issued to the Army’s Unmanned Aerial Vehicle Battalion, known as BANOT, a unit attached to the Army Aviation Command and built specifically to fly and fight with drones.

According to Janes, which reported the acquisition on June 1, the grenades are meant to strike personnel, fortified positions, vehicles, armored vehicles, and installations. In plain terms, Colombia now has thousands of small bombs designed to drop with precision from a drone, and it can make more whenever it wants.

The GADCI and SLAGA, Up Close

The GADCI is a 60 mm high-explosive grenade purpose-built to be released from a drone. Inside it carries about 5 ounces (140 g) of TNT, enough to wreck a light vehicle, collapse a fortified position, or clear personnel in the open without the heavy footprint of an artillery shell.

As Janes reported, precision is the selling point. Indumil claims accuracy to within roughly 3 feet (1 m), with a lethal blast radius of 50 to 80 feet (15 to 25 m). That pairing matters, because a 3-foot drop accuracy lets the operator put the warhead exactly where it needs to go while keeping the blast inside a predictable circle.

Safety lives in the fuse. The grenade uses an MID-70 mechanical spool fuse built under the MIL-STD-331D standard, the arming logic meant to keep a munition inert until it’s actually deployed. The SLAGA is the other half, a carbon-fiber pod that holds one or several grenades and releases them on command, talking to the drone through both mechanical and electrical connections.

The DJI Matrice 300 RTK Doing the Lifting

Here’s the part that says the most about modern warfare. The aircraft carrying these grenades isn’t a purpose-built weapon. It’s the DJI Matrice 300 RTK, the same commercial machine that inspects power lines, maps construction sites, and runs search and rescue around the world.

The Matrice 300 RTK is a workhorse, not a toy. It hauls a payload of about 6 pounds (2.7 kg), stays airborne for roughly 55 minutes, closer to 45 with a real load, and cruises near 51 mph (23 m/s). It holds its control link out to about 9 miles (15 km) on DJI’s OcuSync Enterprise system, and it’s weather-sealed to an IP45 rating with hot-swappable dual batteries that keep it flying through long shifts.

That ruggedness is exactly why it became a favorite of professionals first and militaries second. The drone carries six-directional obstacle sensing and modular mounting points designed for swapping cameras and sensors, and those same mounts make bolting on a SLAGA grenade pod almost trivial. A machine built to carry a survey camera will just as happily carry a bomb.

The irony is hard to miss. DJI is a Chinese company, and its drones are restricted from US government use on security grounds, yet a US-allied military is weaponizing them because nothing else matches DJI on capability for the price. Colombia is developing its own aircraft, the Dragom, but for now the bombs are homegrown and the drones dropping them are Chinese.

Built for Colombia’s War

Colombia has spent decades fighting armed groups across some of the hardest terrain in the hemisphere. The ELN, dissident factions of the former FARC, and the Clan del Golfo all operate in dense jungle and mountains where moving troops is slow and dangerous.

A precise air-dropped grenade is tailor-made for that fight. It lets commanders strike a target in terrain that would cost lives to reach on foot, and it does so with far more control than calling in artillery or a crewed air strike.

There’s a harder reason for the urgency. Armed groups in Colombia have already been using commercial FPV drones to drop their own munitions on soldiers and police. The GADCI is partly an answer to that, a way for the Army to match a threat its enemies brought to the fight first.

The Ukraine Blueprint Comes to Latin America

If a grenade falling from a drone sounds familiar, that’s because it has defined the war in Ukraine. Both sides drop munitions from cheap drones onto trenches, vehicles, and individual soldiers, and that war proved a few hundred dollars of hardware can destroy something worth millions.

Colombia building its own version shows how completely that blueprint has spread. This is no longer a European battlefield experiment. It’s a mass-produced weapon sitting in a Latin American arsenal.

The economics are the whole story. A GADCI paired with a Matrice 300 costs a tiny fraction of a guided missile or a sortie by a crewed aircraft, and Colombia can build the grenades at home by the thousands. When a weapon is that cheap, that precise, and that easy to produce, every military facing an insurgency starts asking why it isn’t doing the same.

DroneXL’s Take

I’ll be direct. This is bigger than a single arms order. A Latin American military just married a homegrown warhead to a Chinese hobby-grade workhorse and fielded thousands of them, and that combination is the whole story of modern warfare in one sentence.

There’s a real case for it. Precision air-dropped munitions can keep soldiers out of ambush-prone valleys and jungle, and 3-foot accuracy with a contained blast is more discriminating than shelling a hillside or kicking in a door. Used carefully, this can mean fewer of Colombia’s troops dying in terrain that has killed them for sixty years.

The hard part is that nobody gets to own this. The same Matrice 300 that drops an Army grenade is the same drone the cartels and guerrillas are already flying, and the GADCI’s logic works just as well in their hands. Colombia is now in a drone arms race with its own insurgents, over hardware anyone can buy and a warhead simple enough to copy.

Building the munition at home makes the capability permanent, and leaning on DJI to carry it makes the dependency obvious. There’s no treaty to sign and no putting this back in the box. Colombia just made drone-dropped munitions a fixed feature of its war, and the rest of the region is watching how it goes.
