'Our weapons are computers': Ukrainian coders aim to gain battlefield edge

In a nondescript office building on the outskirts of Zaporizhzhia, Ukrainian soldiers have been honing what they believed will be a decisive weapon in their effort to repel the Russian invasion. Inside, the weapon glows from a dozen computer screens – a constantly updated portrayal of the evolving battlefield to the south. With one click on a menu, the map is populated with hordes of orange diamonds, showing Russian deployments. They reveal where tanks and artillery have been hidden, and intimate details of the units and the soldiers in them, gleaned from social media. Zooming in shows satellite imagery of the terrain in sharp detail.
