Iran Conflict 2026Background
The Islamic Revolutionary Guard Corps (IRGC) is Iran's ideological military force. It operates separately from the regular Artesh Army and answers to The Supreme Leader. During the 2026 war, the distinction remained operational: the Artesh publicly numbered its own campaign against Gulf bases, while the Guard made separate claims for its attacks.
The corps combines military, maritime, intelligence and domestic-security roles. Its Qods Force is linked to allied armed networks beyond Iran, while the Basij forms part of the domestic security structure. Treasury alleged on 4 September that Golden Global entities facilitated transactions for the Qods Force and supplied correspondent banking access.
The IRGC's naval role gives it particular influence over Hormuz, the waterway joining The Persian Gulf to The Gulf of Oman. Its force can threaten shipping, issue transit demands and turn maritime incidents into strategic pressure. Its practical authority is constrained by foreign naval forces, commercial routing choices and the difficulty of independently verifying rival wartime claims.
Key Issues
Hormuz shipping
The Guard targets commercial shipping
On 5 September, the Islamic Revolutionary Guard Corps (IRGC) said it had struck six vessels, including three tankers it described as using an unauthorised route. Its statement named no ships or locations, and it also acknowledged damage to Iranian tankers. No Independent source confirmed the six claimed strikes.
The claims sit within a longer campaign to impose Iranian control on traffic through the strait of Hormuz. On 12 July, the IRGC struck the container ship GFS Galaxy, damaging its engine room, then declared the strait closed. The attack left one of the ship's eleven Indian crew missing. For the Guard, attacks and closure declarations make commercial transit part of its military pressure campaign, even when its stated control of the waterway is disputed.

How the World Sees Them
Iran
The IRGC is the dominant power centre, having installed the Supreme Leader, neutralised the elected president, and sidelined the Foreign Ministry. Its 31-unit Mosaic Defence absorbed the largest air campaign since World War Two without halting operations.
Israel
Israel's decapitation campaign killed three IRGC commanders in a week but has not disabled the Mosaic Defence. The distributed architecture means no single strike can collapse the system.
Gulf States
IRGC strikes have hit every Gulf state hosting US bases; the 24 April warning to 'neighbouring countries hosting US forces' is a direct threat to Riyadh, Abu Dhabi, Doha, and Manama.
United States
CENTCOM has destroyed 130+ IRGC vessels and struck 9,000+ targets without stopping attack waves. The IRGC's Hormuz toll and claimed drone kill now feature in negotiations as leverage the corps held before the war began.
