The mine-laying robot rolled forward a half-meter across the dusty landscape and halted; its auger-arm drilling down and retracting. Another payload was ejected from an internal hopper into the earthen void. The ‘bot rolled onward, an under-slung plow scraping camouflaging topsoil over the subterranean delivery.
Sunlight glinted off the robot’s age-clouded solar panels, catching a nearby child’s eye. Locals considered ‘Micah 4:3’ an odd name for a tractor model, but it was the mysterious engine’s only marking. It labored silently, planting potatoes in the fields of the war-widowed and lost-limbed like a man drowning his guilt with penitent toil.
