27th Mohammad Rasulullah Division

The Sepah-e Muhammad Rasoul Allah performs military missions through the 27th Mechanized Infantry Operational Division. The Division is a cadre formation, consisting of four battalions. For combat operations, the 27th Division and the 10th and 23rd divisions are augmented by twenty-four Basij Imam Hussein battalions and four Sabirin quick-reaction units.[4]

Basij Imam Hussein battalions are staffed with full-time and salaried Basiji.[5][6]

The metropolitan territory of Tehran is subdivided into 23 municipalities. In each Municipality there is a Basij Resistance District:[4]

• 23 Basij Resistance Districts: each Basij Resistance District controls one Imam Ali Battalion, tasked with riot control and suppression.
• Basij Resistance Precincts: each Basij Resistance Precinct controls two all-male Beit al-Muqaddas Battalions and one all-female Kowsar Battalion. These part-time units are tasked with cultural and cyber operations, urban defense, and search-and-rescue/relief operations.
• Basij Resistance Bases: Basij Resistance Bases are scattered around neighborhoods in mosques, ministries, schools, and other sites. Within each Base, there are two all-male Ashura battalions and one all-female al-Zahra battalion. These units are tasked with cultural and cyber operations, urban defense, and search-and-rescue/relief operations but are staffed with personnel older than Beit al-Muqaddas and all-female Kowsar Battalions.
• 4 Basij Special Forces Fatehin Battalions.[7]^: 8

When deployed, they answer directly to the provincial corps and operate under four citywide IRGC security units:[4]

• Valiasr;
• Hazrat-e Mojtaba;
• Imam Hadi;
• Imam Reza.

These units in turn report to Hazrat-e Zahra and All-e Muhammad brigades, attached to the Sepah-e Muhammad Rasoul Allah.
