Former Ukranian officer Serhii "Flash" Beskrestnov created a Signal channel where military communications specialists could talk with civilian radio experts, [1]reports MIT's Technology Review . But radio communications are crucial for drones, so...

> About once a month, he drives hundreds of kilometers east in a homemade mobile intelligence center: a black VW van in which stacks of radio hardware connect to an array of antennas on the roof that stand like porcupine quills when in use. Two small devices on the dash monitor for nearby drones. Over several days at a time, Flash studies the skies for Russian radio transmissions and tries to learn about the problems facing troops in the fields and in the trenches.

[But] His work has become greatly important to those fighting on the ground, and he recently received formal recognition from the military for his contributions to the fight, with two medals of commendation — one from the commander of Ukraine's ground forces, the other from the Ministry of Defense...

> And given the [2]mounting evidence that both [3]militaries and [4]militant groups in other parts of the world are now adopting drone tactics developed in Ukraine, it's not only his country's fate that Flash may help to determine — but also the ways that armies wage war for years to come.
