Shortly after the September 11 attacks, the United States declared the war on terror and subsequently led a multinational military operation against Taliban-ruled Afghanistan. The stated goal was to dismantle al-Qaeda, which had executed the attacks under the leadership of Osama bin Laden, and to deny Islamist militants a safe base of operations in Afghanistan by toppling the Taliban government. The United Kingdom was a key ally of the United States, offering support for military action from the start of the invasion preparations. The American military presence in Afghanistan greatly bolstered the Northern Alliance, which had been locked in a losing fight with the Taliban during the Afghan Civil War. Prior to the beginning of the United States' war effort, the Taliban had seized around 85% of Afghanistan's territory as well as the capital city of Kabul, effectively confining the Northern Alliance to Badakhshan Province and smaller surrounding areas. The American-led invasion on October 7, 2001, marked the first phase of what would become the 20-year-long War in Afghanistan.
Operation Mountain Fury was a NATO-led operation begun on September 16, 2006 as a follow-up operation to Operation Medusa, to clear Taliban insurgents from the eastern provinces of Afghanistan. Another focus of the operation was to enable reconstruction projects such as schools, health-care facilities, and courthouses to take place in the targeted provinces.
The Battle of Panjwaii was fought in mid-2006 with primarily Canadian and Afghan soldiers, supported by small elements of Dutch, American, and British forces against the Taliban. There were two separate times in which the forces were involved in heavy fighting in the region. The first phase was fought in July 2006, and the second encounter lasted from September to October 2006.
Operation Herrick was the codename under which all British operations in the War in Afghanistan were conducted from 2002 to the end of combat operations in 2014. It consisted of the British contribution to the NATO-led International Security Assistance Force (ISAF), and support to the American-led Operation Enduring Freedom (OEF), within the South Asian country.

The Helmand province campaign was a series of military operations conducted by the International Security Assistance Force (ISAF) forces against Taliban insurgents and other local groups in the Helmand Province of Afghanistan. Their objective was to control a province that was known to be a Taliban stronghold, and a center of opium production. None of the ISAF's intended strategic and political objectives were achieved in the long term.
The Battle of Tarinkot took place in 2001 during the War in Afghanistan. On November 14, 2001, ODA 574 and Hamid Karzai inserted into Uruzgan Province via 4 MH-60K helicopters with a small force of guerrillas. In response to the approach of Karzai's force, the inhabitants of the town of Tarinkot revolted and expelled their Taliban administrators. Karzai traveled to Tarinkot to meet with the town elders. While he was there, the Taliban marshaled a force of 500 men to retake Tarinkot. Karzai's small force plus the American contingent, which consisted of US Army Special Forces from ODA 574 and their US Air Force Combat Controller, Tech Sergeant Alex Yoshimoto, were deployed in front of the town to block their advance. Relying heavily on close air support directed by Yoshimoto, the American/Afghan force managed to halt the Taliban advance and drive them away from the town.
The Fall of Kandahar took place in 2001 during the War in Afghanistan. After the fall of Mazar-i-Sharif, Kabul and Herat, Kandahar was the last major city under Taliban control. Kandahar was where the Taliban movement had originated and where its power base was located, so it was assumed that capturing Kandahar would be difficult. The city fell after several weeks of fighting to a force of local militia under Pashtun military commanders and their American advisers. The fall of Kandahar signaled the end of organized Taliban control of Afghanistan.

The Battle of Shawali Kowt took place near the Arghandab River in Afghanistan during the Invasion of Afghanistan. On December 2, 2001, after a pitched street-by-street battle, the Green Berets and Afghan Freedom Fighters captured the town of Shawali Kowt, but could not gain control over a bridge over the Arghandab River, a gateway to the Taliban spiritual center of Kandahar. That night, the Taliban forces launched a major counterattack, triggering a retreat by the Afghans. Over the next eight hours, the American forces defended against the retreat. U.S. Air Force Sergeant Alex Yoshimoto, the combat controller, orchestrated numerous air strikes from a variety of fighters and bombers, thwarting the Taliban charge and forcing the enemy to retreat.
