Russia revives WWI dazzle paint to throw off Ukraine's AI strike drones

The zebra-striped trucks are a cheap bid to break machine-vision targeting, but Ukrainian drone crews and AI researchers say a fresh paint job buys days, not safety.

Russian military trucks have appeared in black-and-white "dazzle" paint schemes in images circulating on social media over the past week, in what The War Zone described as a low-tech attempt to confuse the machine-vision targeting on Ukraine's AI-guided strike drones. The outlet reported that KAMAZ and Ural cargo trucks have shown up in two patterns, straight zebra stripes and a more organic swirl, applied across the body, wheels and tires.

The tactic borrows from a Royal Navy idea first used in 1917, when dazzle camouflage was meant to break up a ship's outline and make its range and bearing harder for gunners to judge, according to The War Zone. What the Russian trucks are trying to fool now is a camera rather than a human eye. Ukrainian one-way attack drones increasingly classify what they see using onboard object recognition trained on labeled images, and Geert De Cubber, an autonomy specialist at Belgium's Royal Military Academy, told RFE/RL that a vehicle distorted enough to fall outside that training data may not clear the threshold a drone needs before it commits to a strike.

Most experts are doubtful the paint will hold up. Todd Humphreys of the University of Texas told RFE/RL that any single scheme has a short shelf life, because the classifier can be retrained on enough images of dazzle-painted vehicles, at which point the pattern has to change again. Defense Express argued the effort misses the point, noting that machine vision does not estimate range the way the optical rangefinders dazzle was built to defeat, and that an operator using a thermal camera might not register the stripes at all. Ukrainian drone crews were more direct. Major Mykola Kolesnyk, a Ukrainian unmanned-systems regiment commander, told Army TV that his units will hit the vehicles regardless of how they are painted, saying they would strike "these zebras, ostriches, rhinos, whatever they paint themselves as," according to United24.

The paint is a rear-area response to a Ukrainian campaign that has put Russian logistics under fire as far as 200 kilometers behind the front, flown by drones such as the US-made Hornet, which RFE/RL reported costs around $6,000 a unit. Whether the stripes buy Russian supply convoys any cover will come down to how quickly each side can retrain its software or repaint its trucks.
