U.S. troops in Korea practiced turning small drones into weapons with live ordnance last week as the Army works to incorporate unmanned capabilities into the lowest levels of unit formations.

Soldiers with the 2nd Infantry Division/ROK-U.S. Combined Division trained alongside Marines to outfit Neros Archer Strike first-person-view, or FPV, drones with C4 explosives to attack targets at Rodriguez Live Fire Complex in South Korea.

It was the division’s first time using live ordnance with the system.

The training represents part of the military’s broader push to place attack drones directly in the hands of smaller units, giving them the ability to strike targets without relying on assets at higher echelons. Both the Marine Corps and the Army have created specialized units and groups dedicated to the small sky-fliers that have changed the course of modern warfare.

“At my level, the modernization with drones is allowing for on-the-ground troops to, rather than call in company-level or battalion-level assets, within their platoon or squad-sized element, be able to support long-range fires up to 20 kilometers,” said Pfc. Gavin Zerrull, a military intelligence systems maintainer and integrator who participated in the training.

Zerrull is also an FPV coach and operator with Talon Technologies, the “innovation arm” of the 2nd Combat Aviation Brigade, according to the Army’s early August release. The effort assesses unmanned aircraft systems for one-way strike missions, intelligence collection, surveillance and cargo delivery.

The Neros Archer Strike drones are made for long-range missions. As seen in photos released by the Army, the drone is small enough to be carried in one hand, with spindly, spider-like legs and antennas.

According to Zerrull, the platform has already been used in the war between Russia and Ukraine, where drones dominate the battlefield.

“What makes this different from a typical drone training event is the fact that we’re working with live ordnance and using a platform that has actively been tested in real-world situations in Ukraine,” he said.
