An improvised explosive device (IED) is a bomb constructed and deployed in ways other than in conventional military action. It may be constructed of conventional military explosives, such as an artillery shell, attached to a detonating mechanism. IEDs are commonly used as roadside bombs, or homemade bombs.
The Islamic Revolutionary Guard Corps, also known as the Iranian Revolutionary Guards, is a multi-service primary branch of the Iranian Armed Forces. It was officially established by Ruhollah Khomeini as a military branch in May 1979 in the aftermath of the Iranian Revolution. Whereas the Iranian Army protects the country's sovereignty in a traditional capacity, the IRGC's constitutional mandate is to ensure the integrity of the Islamic Republic. Most interpretations of this mandate assert that it entrusts the IRGC with preventing foreign interference in Iran, thwarting coups by the traditional military, and crushing "deviant movements" that harm the ideological legacy of the Islamic Revolution. Currently, the IRGC is designated as a terrorist organization by Bahrain, Canada, Saudi Arabia, Sweden and the United States.
The Quds Force is one of five branches of Iran's Islamic Revolutionary Guard Corps (IRGC) specializing in unconventional warfare and military intelligence operations. U.S. Army's Iraq War General Stanley McChrystal describes the Quds Force as an organization analogous to a combination of the CIA and the Joint Special Operations Command (JSOC) in the United States. Responsible for extraterritorial operations, the Quds Force supports non-state actors in many countries, including Hezbollah, Hamas, Palestinian Islamic Jihad, the Houthi movement, and Shia militias in Iraq, Syria, and Afghanistan. According to Michael Wigginton et al., the Al-Quds Force is "a classic example of state-sponsored terrorism."
The HESA Ababil is an Iranian family of single-engine multirole tactical unmanned aerial vehicles manufactured by Iran Aircraft Manufacturing Industrial Company (HESA). The Ababil comes in four main lines, the Ababil-2 ,3, 4 and 5, of which the Ababil-2 has a number of variants. It is considered a long-range, low-technology drone.
Since the Iranian Revolution in 1979, the Islamic Republic of Iran has been embroiled in tense relations with the U.S. and its allies. Following the hostage crisis, both countries severed relations. Since then, both countries have been involved in numerous direct confrontations, diplomatic incidents, and proxy wars throughout the Middle East, which has caused the tense nature of the relationship between the two to be called an 'international crisis'. Both countries have often accused each other of breaking international law on several occasions. The U.S. has often accused Iran of sponsoring terrorism and of illegally maintaining a nuclear program, as well as using strong rhetoric against Israel, of which Iran has questioned its legitimacy and its right to exist while supporting Hamas, an antizionist terrorist group in the Gaza Strip. Meanwhile, Iran has often accused the U.S. of human rights violations and of meddling in their affairs, especially within the Iranian Democracy Movement.
The war on terror, officially the Global War on Terrorism (GWOT), is a global military campaign initiated by the United States following the September 11 attacks in 2001, and is the most recent global conflict spanning multiple wars. Some researchers and political scientists have argued that it replaced the Cold War.
The Houthi movement, officially the Ansar Allah, is a Zaydi Shia Islamist political and military organization that emerged from Yemen in the 1990s. It is predominantly made up of Zaydi Shias, with their namesake leadership being drawn largely from the Houthi tribe. The group has been a central player in Yemen's civil war, drawing widespread international condemnation for its human rights abuses, including targeting civilians and using child soldiers. The movement is designated as a terrorist organization by some countries.
A Scud missile is one of a series of tactical ballistic missiles developed by the Soviet Union during the Cold War. It was exported widely to both Second and Third World countries. The term comes from the NATO reporting name attached to the missile by Western intelligence agencies. The Russian names for the missile are the R-11, and the R-17Elbrus. The name Scud has been widely used to refer to these missiles and the wide variety of derivative variants developed in other countries based on the Soviet design.
The Axis of Resistance is an informal coalition of Iranian-supported militias and political organizations across the Middle East. Formed by Iran, it unites actors committed to countering the influence of the United States and Israel in the region.
Many states began to intervene against the Islamic State, in both the Syrian civil war and the War in Iraq (2013–2017), in response to its rapid territorial gains from its 2014 Northern Iraq offensives, universally condemned executions, human rights abuses and the fear of further spillovers of the Syrian Civil War. These efforts are called the war against the Islamic State (ISIS) or the international military intervention against Islamic State (ISIS). In later years, there were also minor interventions by some states against IS-affiliated groups in Nigeria and Libya. All these efforts significantly degraded the Islamic State's capabilities by around 2019–2020. While moderate fighting continues in Syria, as of 2025, ISIS has been contained to a manageably small area and force capability.
Operation Inherent Resolve (OIR) is the United States military's operational name for the international war against the Islamic State, including both a campaign in Iraq and a campaign in Syria, with a closely related campaign in Libya. Through 18 September 2018, the U.S. Army's III Armored Corps was responsible for Combined Joint Task Force – Operation Inherent Resolve (CJTF—OIR) and were replaced by the XVIII Airborne Corps. The campaign is primarily waged by American and British forces in support of local allies, most prominently the Iraqi security forces and Syrian Democratic Forces (SDF). Combat ground troops, mostly special forces, infantry, and artillery have also been deployed, especially in Iraq. Of the airstrikes, 70% have been conducted by the military of the United States, 20% by the United Kingdom and the remaining 10% being carried out by France, Turkey, Canada, the Netherlands, Denmark, Belgium, Saudi Arabia, the United Arab Emirates, Australia and Jordan.
The Military of the Islamic State is the fighting force of the Islamic State (IS). The total force size at its peak was estimated from tens of thousands to over 200,000. IS's armed forces grew quickly during its territorial expansion in 2014. The IS military, including groups incorporated into it in 2014, openly operates and controls territory in multiple cities in Libya and Nigeria. In October 2016, it conquered the city of Qandala in Puntland, Somalia. It conquered much of eastern Syria and western Iraq in 2014, territory it lost finally only in 2019. It also has had border clashes with and made incursions into Lebanon, Iran, and Jordan. IS-linked groups operate in Algeria, Pakistan, the Philippines, and in West Africa. In January 2015, IS was also confirmed to have a military presence in Afghanistan and in Yemen.
The Yemeni civil war is an ongoing multilateral civil war that began in late 2014 mainly between the Rashad al-Alimi-led Presidential Leadership Council and the Mahdi al-Mashat-led Supreme Political Council, along with their supporters and allies. Both claim to constitute the official government of Yemen.
Liwa Fatemiyoun, literally "Fatimid Banner", also known as Fatemiyoun Division or Fatemiyoun Brigade, is an Hazara Shia militia formed in 2014 to fight in Syria on the side of the Syrian government prior to the collapse of the Assad regime. The group's officially designated purpose, is the defense of the shrine of Zaynab bint Ali, and to fight "takfiri terrorists" in Syria, which would come to include the Islamic State (IS). It is funded, trained, and equipped by the Islamic Revolutionary Guard Corps (IRGC), and fights under the command of Iranian officers. Both the Fatemiyoun Brigade and the Iranian government downplay their relationship with one another, despite clear coordination and the brigade's operation under the auspices of the IRGC. Liwa Fatemiyoun is also closely associated with Hezbollah Afghanistan.
Iran and Saudi Arabia are engaged in a proxy conflict over influence in the Middle East and other regions of the Muslim world. The two countries have provided varying degrees of support to opposing sides in nearby conflicts, including the civil wars in Syria and Yemen; and disputes in Bahrain, Lebanon, Qatar, and Iraq. The struggle also extends to disputes or broader competition in other countries globally including in West, North and East Africa, South, Central, Southeast Asia, the Balkans, and the Caucasus.
The Islamic State – Yemen Province is a branch of the militant Islamist group Islamic State (IS), active in Yemen. IS announced the group's formation on 13 November 2014.
The Followers of Zainab Brigade, also known as the Zainebiyoun Brigade or Zainebiyoun Division, is a Pakistani Shia Khomeinist militant group actively engaged in the Syrian Civil War. It draws recruits mainly from Shia Pakistanis living in Iran, with some also Shia Muslim communities living in various regions of Pakistan.
