In a jaw-dropping maneuver, Ukraine has launched a bold and unexpected attack into Russia's Kursk region, leaving everyone from military analysts to global onlookers in shock. Over the past 72 hours, what initially seemed like a small raid has evolved into a substantial military operation with significant implications. Surprise in military operations is a powerful force multiplier. When executed flawlessly, it can render the opponent incapable of a timely response. Ukraine's recent actions exemplify this, catching Russia completely off guard and allowing Ukrainian forces to penetrate deep into Kursk. Unlike Russia's earlier attempts around Kharkiv, Ukraine has employed a swift, armored approach reminiscent of their successful Thunder Run in late 2022.
