The Basij were initially engaged in assisting the Revolutionary Guards and the Revolutionary Committees (disbanded in the early 1990s) to secure law and order in major population centers. The auxiliary military unit also aided the central government in fighting against Baluchi, Kurdish and Turkoman separatists in remote regions. But their role shifted after Iraq’s 1980 invasion. As the war took its toll on Iranian forces, the poorly trained Basij were deployed alongside the regular Iranian military.
They were often used in “human wave” tactics, in which they were deployed as cannon fodder or minesweepers, against Iraqi forces. Mobilization of Basij for the war-front peaked in December 1986, when some 100,000 volunteers were on the front. The Basij were often criticized for mobilizing child soldiers for the war effort and using children for “martyrdom” operations.
After the war ended in 1988, the Basij became heavily involved in post-war reconstruction. But their role increasingly shifted back to security as a political reform movement flowered in the late 1990s. The Basij became a policing tool for conservatives to check the push for personal freedoms, particularly among students and women. The Basij were mobilized in 1999 to put down anti-government student protests and to further marginalize the reform movement.
Since the 2005 election of President Mahmoud Ahmadinejad, Basij interventions in politics have become more frequent. The Basij were pivotal in suppressing the anti-government protests after the disputed presidential election on June 12, 2009. Various branches of the Basij were mobilized to counter anti-government protests at high schools, universities, factories and on the street. Yet the Basij also performed poorly, as they were unable to suppress demonstrations through their local branches. The Iranian press reported that neighborhood Basij were not willing to beat up neighbors who protested against the election result by chanting “God is great” from their homes. Some Basij members at high schools and universities also reportedly deserted their assignments after commanders chiefs tried to mobilize them to intimidate, harass or beat up fellow students engaged in sit-ins and demonstrations against the election results. And many Basij members evaporated in the face of angry demonstrators in major population centers. Basij and IRGC commanders reported transporting Basij members from outside towns to counter dissidents as the local Basij members were not ready to act in their own neighborhoods or place of work.
