Create a dramatic, high-contrast poster in the style of 1940s Soviet wartime propaganda. The composition should feature a heroic soldier with helmet standing tall atop a ruined battlefield, holding a fluttering red flag emblazoned with the hammer and sickle. Behind him, silhouettes of tanks and aircraft surge forward, symbolizing unstoppable Soviet strength. The background should include rays of sunlight breaking through storm clouds, casting a divine glow on the soldier’s face. Use a limited color palette dominated by red, black, and gold, with bold Cyrillic text at the bottom reading: 'За Родину! За Сталина!' (‘For the Motherland! For Stalin!’). The style should mimic vintage lithographic printing with strong geometric shapes, dynamic angles, and a sense of motion and urgency."
