One sunny day in eastern Ukraine, two grown men in pixel camouflage sit together in the shade of lush summer bushes on the edge of a field, playing what looks to be a highly immersive virtual reality video game. Fourty-four-year-old Yegor “Yeti,” wearing futuristic first-person goggles and holding a controller with a relaxed grip, soars over apple green fields, saturated with shell holes, towards his target. Beside him, Yegor’s spotter watches the live stream silently on two screens.
