Iran Renames Quds Force Assassination Unit 840 as Unit 600 With Expanded Regional Structure

BLUFRenaming Unit 840 preserves Iran's extraterritorial assassination capability under a fresh label, creating an immediate gap in Western sanctions and watchlist frameworks built around the old designation.

Iran International reported on October 13, citing two sources close to the Quds Force, that Unit 840 was renamed Unit 600 after its personnel and structure were exposed, and that Quds Force commander Esmail Qaani appointed Mojtaba Hagh-Lesan, 64, the unit's former intelligence chief, to lead it 1. The report says Hagh-Lesan replaces Yazdan Mir, killed in an Israeli strike on April 6, and the unit has had no commander since 1. A leaked command chart names Mohammad Reza Ansari as deputy for Israel, Mohsen Boroujeni for the United States and Europe, Morteza Babaei for the Middle East and Africa, and Javad Sharfaei for Asia 12. Israel Hayom and The Yeshiva World relayed the report on October 14 23; CommandEleven noted on October 21 that no government has confirmed the renaming 4.

Analysis
Iran's Quds Force has kept its external assassination arm intact and reorganized it by region, with named desks for Israel, the United States and Europe, the Middle East and Africa, and Asia. Reliance on veteran figures like Hagh-Lesan points to a thin command bench after the April losses, though the deniable-intermediary recruiting model does not depend on any single commander. Western counterterrorism and sanctions authorities that listed Unit 840 and Ansari now face a successor name that may fall outside existing designations. Confidence is low: Iran International is the only original reporting, resting on two unnamed sources and an unpublished chart, and the outlets that relayed it add nothing independent. No government has confirmed the renaming, the chart, or Mir's death. The report may be an opposition-outlet product, or a Quds Force disclosure meant to project reach, and Unit 600 may be an internal relabel with no operational change.
