The Gendarmerie, numbering nearly 74,000 in 1979, was subordinate to the Ministry of Interior. Its law enforcement responsibilities extended to all rural areas and to small towns and villages of fewer than 5,000 inhabitants. The International Institute for Strategic Studies estimated its manpower at 70,000 in 1986.

The National Police operated with approximately 200,000 men in 1979, a figure that has not fluctuated much since. Like the Gendarmerie, the National Police was under the Ministry of Interior, and its responsibilities included all cities with more than 5,000 in population--a total of 20 percent of the population. In addition, the National Police was responsible for passport and immigration procedures, issuance and control of citizens' identification cards, driver and vehicle licensing and registration, and railroad and airport policing. Some of these duties were absorbed into the Ministry of the Pasdaran during the early years of the Revolution, and cooperation between these two branches seemed extensive.

Since 1979 both these paramilitary organizations have undergone complete reorganizations. IRP leaders quickly appointed Gendarmerie and police officers loyal to the Revolution to revive and reorganize the two bodies under the Republic. Between 1979 and 1983, no fewer than seven officers were given top National Police portfolios. Colonel Khalil Samimi, appointed in 1983 by the influential Hojjatoleslam Nategh-e Nuri, then minister of interior, was credited with reorganizing the National Police according to the IRP's Islamic guidelines. The Gendarmerie followed a similar path. Seven appointments were made between 1979 and 1986, leading to a full reorganization. In addition to Brigadier General Ahmad Mohagheghi, the commander in the early republican period who was executed in late summer of 1980, five colonels were purged. Colonel Ali Kuchekzadeh played a major role in reorganizing and strengthening the Gendarmerie after its near collapse in the early revolutionary period. The commander in 1987, Colonel Mohammad Sohrabi, had served in that position since February 1985 and was the first top officer to have risen from the ranks.

As of 1987, the National Police and the Gendarmerie reflected the ideology of the state. Despite their valuable internal security operations, the roles of both bodies were restricted by the rising influence of the Pasdaran and the Basij.
