In Ukraine, expansive trench networks are being left behind, according to Nick Reynolds, a research fellow for Land Warfare at the Royal United Services Institute think-tank. “If you speak to Ukrainians, some will say, ‘Nobody digs trenches any more.’ There is an element of truth in that. In some areas, we’re not seeing trenches at all on the battlefield.”
