Experts Credit Mohammad Ali Jafari’s Mosaic Defence Doctrine for Building Iran’s Military Resilience

Mohammad Ali Jafari, the architect of Iran’s “Mosaic Defence,” is credited with creating a military doctrine designed to ensure the Islamic Republic can continue fighting even under severe attacks on its leadership. The concept has been credited with sustaining Iran’s resilience during recent conflicts, including Operation Epic Fury, which aimed to topple Tehran’s regime but failed to paralyse Iranian military operations.

Jafari, a former commander-in-chief of the Islamic Revolutionary Guard Corps (IRGC) from 2007 to 2019, joined the IRGC after the 1979 Islamic Revolution. He initially served in an intelligence unit in Iran’s Kurdistan province and gradually rose through the ranks, participating in the Iran-Iraq War (1979–1989) and later overseeing the Guards’ ground forces and the elite Sarallah unit. In 2005, he became director of the IRGC’s Centre for Strategic Studies, where he began formalizing the Mosaic Defence doctrine, incorporating lessons from regional conflicts and the 2003 US-led invasion of Iraq.

The Mosaic Defence concept decentralizes Iran’s military power into multiple semi-independent layers rather than relying on a single command chain, which could be disabled by a decapitation strike. It integrates IRGC provincial commands, the Basij, the regular army, missile units, naval forces, and local command structures. Each provincial command operates autonomously, maintaining weapons, intelligence, and decision-making capacity even if disconnected from central leadership.

Experts note that this structure makes Iran’s defence more resilient and harder to degrade. Dr. Michael Connall stated that the restructuring was intended to “make any attempt at degrading Iran’s defence exceedingly difficult.” The doctrine also leverages Iran-backed groups known as the “Axis of Resistance,” which could act independently in the event of conflict with stronger adversaries such as the United States or Israel.

The doctrine’s two central aims are to prevent the collapse of command structures and to prolong battlefield resistance through layered defence, irregular warfare, local mobilisation, and attrition. This approach reflects Iran’s strategic lessons from regional shocks, including the rapid collapse of Saddam Hussein’s regime in Iraq and the US invasion of Afghanistan in 2001.

By designing a distributed military system, Jafari ensured that Iran’s defence capabilities could survive the loss of senior leaders or key units, making conventional military strategies against the country more complex. The Mosaic Defence represents a long-term, adaptive strategy aimed at preserving Iran’s sovereignty and operational flexibility under extreme conditions.
