Operation Enduring Freedom: A Comprehensive Overview

Nov 07, 2025 0

Operation Enduring Freedom (OEF), spanning from October 7, 2001, to December 31, 2014, represents a crucial phase of the War in Afghanistan (2001-2021) and related military operations within the broader Global War on Terrorism. The term "OEF" typically refers to the phase of the War in Afghanistan from 2001 to 2014.

Following the terrorist attacks on September 11, 2001, in New York City and Washington D.C., President George W. Bush declared a war on terror. On 7 October 2001, in response to the September 11 attacks, President George W. Bush initiated Operation Enduring Freedom. The initial military objectives of OEF, as articulated by President George W. Bush, aimed to dismantle al-Qaeda and remove the Taliban regime that harbored the terrorist group.

The Taliban and Al-Qaeda Alliance

Seizing upon a power vacuum after the Soviets withdrew from Afghanistan after their invasion, the Taliban governed Afghanistan from 1996 to 2001. Their extreme interpretation of Islamic law prompted them to ban music, television, sports, and dancing, and enforce harsh judicial penalties (See Human rights in Afghanistan).

In 1996, Saudi dissident Osama bin Laden moved to Afghanistan. When the Taliban came to power, bin Laden was able to forge an alliance between the Taliban and his al-Qaeda organization. It is understood that al-Qaeda-trained fighters known as the 055 Brigade were integrated with the Taliban army between 1997 and 2001.

President George W. Bush stated that Osama bin Laden was behind the 11 September attacks in 2001.

Military Operations in Afghanistan

On Sunday 7 October 2001, American and British warplanes began fighting Taliban forces and al-Qaeda. The Northern Alliance, aided by Joint Special Operations teams consisting of Green Berets from the 5th Special Forces Group, aircrew members from the 160th Special Operations Aviation Regiment (SOAR), and Air Force Combat Controllers, fought against the Taliban.

Through bombing and massive defections, they captured Mazar-i-Sharif on 9 November. They then rapidly gained control of most of northern Afghanistan, and took control of Kabul on 13 November after the Taliban unexpectedly fled the city. The Taliban were restricted to a smaller and smaller region, with Kunduz, the last Taliban-held city in the north, captured on 26 November. The war continued in the south of the country, where the Taliban retreated to Kandahar.

Whilst in Kandahar the Taliban agreed to surrender but the deal was rejected by Secretary of Defense Donald Rumsfeld as it would have provided amnesty to Taliban leader Mullah Mohammed Omar. After Kandahar fell in December, remnants of the Taliban and al-Qaeda continued to mount resistance. However, success in quelling the Taliban insurgency since the 2001 invasion has faltered. On 15 August 2021, all of Afghanistan, besides Kabul, was back in the hands of Taliban.

The United States was supported by several nations during Operation Enduring Freedom (OEF) in Afghanistan in 2001-2003 and in subsequent coalition operations directly or indirectly in support of OEF.

On 9 October 2004, Afghanistan elected Hamid Karzai president in its first direct elections. The following year, Afghans conducted the 2005 Afghan parliamentary election on 18 September. While military forces interdicted insurgents and assured some form of security, Provincial reconstruction teams were tasked with infrastructure building, such as constructing roads and bridges, assisting during floods, and providing food and water to refugees.

Many warlords have participated in an allegiance program, formally recognizing the legitimacy of the government of Afghanistan, and formally surrendering their soldiers and weapons.

GEN Tommy Franks (2001-2003)
GEN John Abizaid (2003-2007)
ADM William J.

Operation Enduring Freedom - Philippines

In January 2002, over 1,200 soldiers from the United States Special Operations Command Pacific (SOCPAC) deployed to the Philippines to support the Armed Forces of the Philippines (AFP) in their push to uproot terrorist forces on the island of Basilan.

The Abu Sayyaf Group (ASG) Al Harakat Al Islamiyya, is deemed a "foreign terrorist organization" by the United States government. Jemaah Islamiyah is a militant Islamic terrorist organization dedicated to the establishment of a fundamentalist Islamic theocracy in Southeast Asia, in particular Indonesia, Singapore, Brunei, Malaysia, the south of Thailand and the Philippines. Jemaah Islamiyah is thought to have killed hundreds of civilians. Also, it is suspected of carrying out the Bali car bombing on 12 October 2002, in which suicide bombers attacked a nightclub killing 202 people and wounding many more. Most of the casualties were Australian tourists. State Department designated Jemaah Islamiyah as a Foreign Terrorist Organization.

In January 2002, 1,200 Members of United States Special Operations Command, Pacific (SOCPAC) were deployed to the Philippines to assist the Armed Forces of the Philippines (AFP) in uprooting al-Qaeda, Jemaah Islamiyah and Abu Sayyaf. The United States Special Forces (SF) Unit trained and equipped special forces and scout rangers of the AFP, creating the Light Reaction Company (LRC). The LRC and elements of SOCPAC deployed to Basilan on completion of their training.

The desired result was for the AFP to gain sufficient capability to locate and destroy the ASG, to recover hostages and to enhance the legitimacy of the Philippine government. The humanitarian portion of the operation, Operation Smiles, created 14 schools, 7 clinics, 3 hospitals and provided medical care to over 18,000 residents of Basilan.

Operation Enduring Freedom - Horn of Africa (OEF-HOA)

In October 2002, the Combined Task Force 150 and United States military Special Forces established themselves in Djibouti at Camp Lemonnier. Unlike other operations contained in Operation Enduring Freedom, OEF-HOA does not have a specific terrorist organization as a target. OEF-HOA instead focuses its efforts to disrupt and detect terrorist activities in the region and to work with host nations to deny the reemergence of terrorist cells and activities.

The stated goals of the operation were to provide humanitarian aid and patrol the Horn of Africa to reduce the abilities of terrorist organizations in the region. The military aspect involves coalition forces searching and boarding ships entering the region for illegal cargo as well as providing training and equipment to the armed forces in the region.

Operations began in mid-2002 at Camp Lemonnier by a Combined Joint Special Operations Task Force (CJSOTF) augmented by support forces from Fort Stewart, Fort Hood, and Fort Story. In October 2002, the Combined Joint Task Force, Horn of Africa (CJTF-HOA) was established at Djibouti at Camp Lemonnier, taking over responsibilities from the CJSOTF.

Military and Special Operations Forces (SOF), and coalition force members, Combined Task Force 150 (CTF-150). The coalition force consists of ships from Australia, Canada, France, Germany, Netherlands, India, Italy, Pakistan, New Zealand, Spain, Turkey and the United Kingdom.

The primary goal of the coalition forces is to monitor, inspect, board and stop suspected shipments from entering the Horn of Africa region. Military also conducts operations targeting Al-Qaeda-linked fighters in Somalia, these operations had reportedly killed between 113 and 136 militants by early 2016.

CJTF-HOA has devoted the majority of its efforts to train selected armed forces units of the countries of Djibouti, Kenya and Ethiopia in counterterrorism and counterinsurgency tactics. Humanitarian efforts conducted by CJTF-HOA include the rebuilding of schools and medical clinics, as well as providing medical services to those countries whose forces are being trained.

Anti-piracy operations were undertaken by the coalition throughout 2006 with a battle fought in March when US vessels were attacked by pirates. In January 2007, during the war in Somalia, an AC-130 airstrike was conducted against al-Qaeda members embedded with forces of the Islamic Courts Union (ICU) operating in southern Somalia near Ras Kamboni.

US naval forces, including the aircraft carrier USS Dwight D. Eisenhower, were positioned off the coast of Somalia to provide support and to prevent any al-Qaeda forces escaping by sea.
