The residents of Sant Climent Sescebes, a small town of about 700 inhabitants in the Alt Empordà region, are accustomed to the sounds of gunfire and explosions in the distance. Less than a kilometer away lies the Spanish army's training base, the only one in Catalonia where soldiers conduct live-fire exercises and maneuvers with explosives. Every week, the soldiers carry out exercises with live ammunition, and occasionally, other forces such as the Civil Guard, the Mossos d'Esquadra (Catalan police), or, in recent months, even elite squadrons of the Ukrainian army, also come to the 1,300-hectare training ground.
