Kabul is the capital and largest city of Afghanistan.
Tony Stark returned to Afghanistan during his early quest of establishing world peace, using his newly created identity as Iron Man. Stark sent a Magna-Drone, one of his patent pending designs, in order to clean several square miles of a Land mine-infested desert outside of Kabul.
Stark launched the Magna-Drone to follow him as he flew in his Iron Man Armor, activating it once it reached a safe altitude. The Magna-Drone was able to attract the landmines with a 100% retrieval and non-detonation rate, making Stark wanting to travel to Tokyo to celebrate the success.
