## Prediction

In the first 24 hours of the US convoy operation, Iran-linked forces are likely to conduct calibrated harassment such as overflights by UAVs, laser rangefinding, and swarming approaches by small boats to test US rules of engagement. These actions are designed to generate domestic and regional propaganda value and signal that Iran still exerts influence over the chokepoint without triggering overwhelming US retaliation. The risk of an unplanned kinetic incident, such as shots fired at an approaching boat or downing of a drone, will be elevated but still below the threshold of a broader engagement. Iran will likely avoid overt mining or direct missile strikes at this early stage.

## Drivers

- IRGC-linked radio threats to ships off Ras Al Khaimah and prior drone attack on a merchant vessel
- Azizi’s public warning that US interference is a ceasefire violation
- Historical IRGC pattern of harassment tactics (fast boats, UAVs) short of open warfare
