Between 2001 and 2021, soldiers from many countries, including the US, UK, Canada, Denmark, and Estonia, risked their lives in Afghanistan. Their mission began after the 9/11 attacks when NATO invoked Article 5 for the first time, treating an attack on the US as an attack on all allies. The Taliban, who sheltered al-Qaeda, were quickly pushed from power by US forces and allies. But the fight continued for two decades. Early missions saw slow, careful flights into bases like Kandahar and Kabul to avoid Taliban missile attacks. The first years were quiet, but danger stayed. Soldiers patrolled in old armored vehicles, and Taliban rockets hit remote bases. Things heated up after 2006, especially when the UK sent strong forces to Helmand province, where they met fierce resistance. British paratroopers called in mortar fire dangerously close to their own positions to keep the Taliban from overrunning their bases. The fighting involved close combat and constant threats from expertly hidden Improvised Explosive Devices (IEDs), which caused severe injuries and deaths. Soldiers prayed they would survive blasts with less serious amputations. The war was not just an American effort. Many nations stood shoulder to shoulder against the Taliban and al-Qaeda. Afghan soldiers and civilians also fought and sacrificed greatly over these years. The story of Afghanistan is one of bravery, hardship, and resilience. Despite the risks and losses, many turned their shattered lives into stories of courage. These sacrifices answer the call for help after 9/11 and challenge any claims that troops avoided battle.
