The Badr Organization, previously known as the Badr Brigades or Badr Corps, is an Iraqi Shia Islamist and Khomeinist political party and paramilitary organization headed by Hadi al-Amiri. The Badr Brigade, formed in 1982 and led by Iranian officers, served as the military arm of the Supreme Council for Islamic Revolution in Iraq (SCIRI), a Shia Islamic party based in Iran. The Badr Brigade was created by Iranian intelligence and Shia cleric Mohammad Baqir al-Hakim with the aim of fighting the Ba'athist regime of Saddam Hussein during the Iran–Iraq War. Since the 2003 US-led invasion of Iraq, most of the Badr Brigade fighters have entered the new Iraqi army and police force. Since 2003, the Badr Brigade and SCIRI were considered to be one party, but have recently unofficially separated with the Badr Organization now being an official Iraqi political party. Badr Brigade forces, and their Iranian commanders, have come to prominence in 2014 fighting the Islamic State of Iraq and the Levant (ISIL) in Iraq. It is a part of the Popular Mobilization Forces.
The term militia in contemporary Iraq refers to armed groups that fight on behalf of or as part of the Iraqi government, the Mahdi Army and Badr Organization being two of the biggest. Many predate the overthrow of Saddam Hussein, but some have emerged since, such as the Facilities Protection Service. The 2003 invasion of Iraq by United States-led forces undermined the internal order in the country and brought about, among other things, the establishment of several pro-Iranian militias affiliated with the Islamic Revolutionary Guard Corps's Quds Force. The militias were set up with the purpose of driving the U.S. and Coalition forces out of Iraq and establishing Iranian involvement in the country. Prominent among the militias are Asa'ib Ahl al-Haq, Kata'ib Hezbollah and Harakat al-Nujaba.
Kata'ib Hezbollah, also known as the Hezbollah Brigades, is a radical Iraqi Shiite paramilitary group which is a part of the Iraqi Popular Mobilization Forces (PMF), staffing the 45th, 46th, and 47th Brigades. During the Iraq War (2003–11), the group fought against Coalition forces. It has been active in the War in Iraq (2013–2017) and the Syrian Civil War. The group was commanded by Abu Mahdi al-Muhandis until he was killed in a US drone attack in 2020. Thereafter, Abdul Aziz al-Muhammadawi became the new leader of the PMF. The group seeks to establish an Iran-aligned government in Iraq, expel American forces from the country, and advance the regional and international interests of Iran in Iraq and the region. The group is responsible for killing hundreds of U.S. soldiers and takes a central part in carrying out attacks against U.S. targets in Iraq and acts as part of the Axis of Resistance. Kata'ib Hezbollah has received extensive training, funding, logistic support, weapons, and intelligence from the IRGC's overseas military-intelligence service Quds Force.
Qais Hadi Sayed Hasan al-Khazali is an Iraqi politician and militant leader who is the founder and Secretary-General of the Asa'ib Ahl al-Haq, an Iraqi Shi'ite paramilitary organization and political party.

As head of the Special Groups, Khazali directed arms shipment, formation of squads to participate in fighting, and insurgent operations, most notably the 20 January 2007 attack on American forces in Karbala. A former follower of Muqtada al-Sadr, he was expelled from the Mahdi Army in 2004 for giving "unauthorized orders" and founded his own group: Asa'ib Ahl al-Haq (AAH) also known as the "Khazali Network" that was later designated as a terrorist group by the U.S. Department of State.

An arrest warrant was issued for him by the Central Criminal Court of Iraq on 12 April 2005 with a reward of $200,000 for information leading to his capture. In 2006 he was added to the Iraqi government's 41 Most-Wanted list. He holds both Iraqi and Iranian nationalities because he lived in exile in Iran during Saddam Hussein's rule, and later returned there to live in Tehran after 2006.

The Sheibani Network was an Iraqi smuggling network and Shi'a Insurgent group led by Abu Mustafa al-Sheibani, an ex-commander of the Supreme Council for Islamic Revolution in Iraq's Badr Brigades. The Badr Brigades' militiamen and supply lines became known collectively as the “Sheibani Network,” which maintained links to Asa'ib Ahl al-Haq (AAH) and to Kata'ib Hezbollah. The group was believed to be used by Iran's Revolutionary Guards' Quds Force to supply Iraqi Special Groups. The group is alleged to be responsible for numerous attacks on Iraqi and Coalition forces. In 2009 the American Enterprise Institute believed that the network consisted of 280 members, divided in 17 units. US commanders estimated that weapons smuggled and used by the group were responsible for the death of 170 and injuries to 600 American soldiers by February 2007. Beginning in February 2013, reports from Iraqi newspapers Al Masalah and Kitabat claimed splits had emerged within Kata'ib Hezbollah, leading to the expulsion of al-Sheibani as its leader. In May 2013 al-Sheibani founded Kata'ib Sayyid al-Shuhada, but retired from his role as leader in 2014 when he became an advisor to Iraqi Interior Minister Mohammed Al-Ghabban.
The Iranian intervention in Iraq has its roots in the post-2003 invasion of Iraq by the United States and its allies, when the infrastructure of the Iraqi armed forces, as well as intelligence, were disbanded in a process called "de-Ba'athification" which allowed militias with close ties to Tehran to join the newly reconstituted army.

The U.S. Department of Defense said the operation was in retaliation for repeated attacks on Iraqi military bases hosting Operation Inherent Resolve (OIR) coalition forces, particularly the 27 December 2019 attack on a Kirkuk airbase that left an American civilian contractor dead. Kata'ib Hezbollah, an extremist Shi'ite militia funded by Iran, denied any responsibility for the attacks.

The 2003 invasion of Iraq, which toppled Iraqi president Saddam Hussein and his Arab Socialist Ba'ath Party, was the decisive event that allowed Iran to begin exerting an unprecedented level of influence on Iraqi politics. Leveraging the fact that Shia Muslims account for the majority of the population in both countries, the Iranian government used Shia militias to serve Iran's interests during the Iraq War. This culminated in Iran's involvement in the Iraqi insurgency, in which there were instances of Shia militants engaging the Multi-National Force in direct combat. Organizations that enjoyed large-scale Iranian support included the Mahdi Army of Muqtada al-Sadr, as well as Kata'ib Hezbollah, Asa'ib Ahl al-Haq, and the Promised Day Brigade. Since 2007, the United States has employed a "kill or capture" strategy with regard to confronting Iranian operatives in the Iraqi conflict.
