1On September 22nd, 980, with Iraq's formal invasion of Iran, the Iran-Iraq war broke out. At the beginning of the war, because Iran was basically unprepared, the Iraqi army advanced rapidly. However, with the extension of the front and the arrival of winter, the Iraqi army struggled to survive. Iranian counterattacks were launched in Abadan in September of 198 1 after surviving the inadaptability at the beginning of the war. However, due to the well-prepared Iraqi army, although some achievements have been made, Iran's own losses are also great, especially the mines in front of the Iraqi army positions have caused great losses to Iranian tank forces. So when Iran launched its victorious offensive in March 1982, it used more than 10000 teenagers aged 15 to 16 to level the minefield. These teenagers hung plastic keys issued by their superiors around their necks to open the gates of heaven, shouted the slogan "God is great", and set off mines in rows with their own bodies, clearing the way for tank attacks. Then 30,000 regular troops and 100000 revolutionary guards crossed the minefield, quickly broke through the Iraqi defense line, annihilated 25,000 Iraqi troops, and captured 15000 people to turn the tide. Since then, the war has entered a stalemate stage.
