The Basij: Iran’s Paramilitary Vanguard

Founded in 1979 by Ayatollah Ruhollah Khomeini, the Basij (Organization for Mobilization of the Oppressed) stands as a crucial component of Iran’s security apparatus. Functioning as a volunteer paramilitary militia under the Islamic Revolutionary Guard Corps (IRGC), the Basij serves as both a grassroots ideological enforcer and an auxiliary fighting force. While portrayed by Iranian officials as defenders of the revolution, the organization has faced international scrutiny for its role in domestic repression and regional interventions.

Origins and Early History (1979–1988)

Khomeini established the Basij shortly after the 1979 Islamic Revolution, aiming to create a “people’s army” of volunteers. Initially drawing support from impoverished, rural, and religiously devout communities, the Basij prioritized ideological commitment over professional military training. During the Iran-Iraq War (1980–1988), Basij volunteers, including teenagers, played a significant role in military operations, often participating in “human wave” assaults. [1]

Structure and Membership

The Basij operates as one of five branches within the IRGC. [1] Membership is open to individuals aged 18 to 45, though volunteers as young as 12 and older individuals have participated in the past, particularly during the Iran-Iraq War. [1] As of July 2019, Gholamreza Soleimani held the position of commander, though some reports suggest Mojtaba Khamenei wields unofficial command. [1] The organization boasts a vast reserve force exceeding 25 million volunteers, with approximately 600,000 available for immediate deployment. [1]

Roles and Responsibilities

The Basij’s functions extend beyond military support. It is actively involved in internal security, law enforcement, and moral policing. [1] The organization also provides aid during natural disasters and other emergencies. [1]

Recent Events and the 2026 US-Israel Strikes

Recent events, including the death of Ayatollah Ali Khamenei in March 2026, have sparked both concern and hope among Iranians. [3] The strikes on Tehran, which targeted internal security and Basij command centers, [4] have led to a sense of anticipation for potential regime change among some Iranians, particularly those who experienced life under strict religious rule and limited freedoms. [2]

Budget and Staffing

In 2016, the Basij’s budget was reported at $357.08 million. [1] Estimates of its staffing levels vary, with the Center for Strategic and International Studies (CSIS) estimating 90,000 personnel in 2005. [1]
