Back in May, Ukrainian developers revealed a new armed ground robot—the Fury. Four months later, a Fury has fought—and reportedly won—the type’s first major skirmish. On or just before Thursday, one of the four-wheeled, shopping-cart-sized Furies assaulted a trench in Russia’s Kursk Oblast.

In analyzing the Kursk offensive, seventeenth-century maps may be less helpful than more recent history. With its trench lines, artillery barrages, and grinding attrition, the war in Ukraine is often likened to World War I.
