Military of ISIL. The military forces of the Islamic State of Iraq and the Levant (ISIL) constituted a hybrid organization blending conventional military structure with insurgent tactics. At its peak between 2014 and 2017, it controlled vast territories in Iraq and Syria, functioning as a proto-state army. Its operations were characterized by extreme violence, sophisticated media propaganda, and significant external funding, posing a major challenge to regional governments and a U.S.-led international coalition.

Structure and organization

The military was organized under a centralized command led by the Caliph, initially Abu Bakr al-Baghdadi, with authority delegated through a provincial system. Key components included the regular army, known as the *Junud al-Khilafah*, and internal security apparatuses like the Amniyat. The structure featured distinct branches for infantry, artillery, armour, and a dedicated religious police unit, the Hisbah. Key military councils, such as the Military Council and the Security Council, oversaw strategy and operations across provinces like Nineveh and Raqqa.

Personnel and recruitment

At its zenith in 2014, ISIL mobilized an estimated 100,000 personnel from diverse sources. Recruitment aggressively targeted foreign jihadists, drawing thousands from across Europe, the Caucasus, North Africa, and the Middle East to regions like Syria. The group also coerced recruitment from local populations in captured cities like Mosul and Fallujah, and integrated former officers from Saddam Hussein's Iraqi Army. Notable commanders included Abu Muslim al-Turkmani and Abu Ali al-Anbari, while specialized roles were filled by experts from the Chechen conflict and veterans of the War in Afghanistan (2001–2021).

Equipment and funding

ISIL amassed a vast arsenal largely through capture from opposing forces, notably during the 2014 offensive against the Iraqi Army which yielded U.S.-made equipment, artillery pieces, and Humvees in Mosul. Funding streams were multifaceted, including revenue from captured oil fields in Deir ez-Zor, taxation and extortion in controlled cities, bank looting in Tikrit, ransom payments from kidnapping, and donations from sympathetic networks in the Gulf states. This financial engine funded salaries, weapons procurement via black markets in Turkey, and complex logistics.

Tactics and operations

The group employed a brutal mix of conventional combined arms offensives and asymmetric warfare. Early blitzkrieg-style operations, such as the capture of Mosul, demonstrated conventional capabilities. It pioneered extensive use of improvised explosive devices, suicide attacks using vehicle-borne improvised explosive devices, and urban warfare techniques seen in the Battle of Ramadi (2014–2015). Notorious for war crimes, including the Sinjar massacre against the Yazidis and public executions, its operations also included complex terrorist attacks abroad, such as those in Paris and Brussels.

Ideology and propaganda

Military actions were inseparable from the group's Salafi-jihadist ideology, which sought to establish a global Caliphate. This was propagated by sophisticated media wings like Al-Hayat Media Center and Amaq News Agency, which produced high-quality videos of battles, executions, and life in the so-called state. Propaganda celebrated military victories in *Dabiq* and *Rumiyah* magazines, often featuring messages from spokesmen like Abu Muhammad al-Adnani, to inspire recruits and intimidate adversaries like the Syrian Democratic Forces and the International coalition against ISIL.

Decline and legacy

The military decline began with major territorial losses following counter-offensives by the Iraqi Security Forces, the Syrian Democratic Forces, and Operation Inherent Resolve. Decisive defeats occurred at the Battle of Mosul (2016–2017) and the Battle of Raqqa (2017), which destroyed its proto-state. By 2019, after the death of Abu Bakr al-Baghdadi in Barisha, it reverted to a diffuse insurgency across Iraq and Syria, with fragmented cells still conducting attacks. Its legacy includes a model for hybrid terrorist-armies, a persistent transnational threat, and profound regional destabilization that reshaped conflicts involving Turkey, Iran, and Russia.
