Ukraine's audacious incursion into Russia's Kursk region marks the largest attack on Russian territory since World War II, seizing 1,000 square kilometers and capturing hundreds of Russian soldiers. This offensive has exposed significant weaknesses in Russia's border defenses and caused a strategic shift in the conflict. In response, Russia has bolstered its border defenses and evacuated thousands of civilians from affected areas. Ukrainian forces have demonstrated innovative tactics, including the use of drones and electronic warfare, to advance their positions. The incursion has also sparked an increase in job advertisements for trench diggers as Russia scrambles to fortify its borders. The operation's long-term goals remain unclear, but it has significantly altered the battlefield dynamics.
