The Taliban have showcased some of the American military hardware they captured during their takeover of Afghanistan. During the military parade, a long line of Humvee and other armored vehicles, flying white-and-black Taliban flags, drove a highway outside the city of Kandahar. The parade was held to celebrate the exit of US troops from Afghanistan. The Taliban also flew an Afghan army Black Hawk helicopter during celebrations. The last remaining US troops left the country late Monday to end their 20-year invasion.
