A new report reveals that the US Marine Corps has been conducting intensive training against full-scale mockups of advanced air-defense systems closely resembling the Russian S-300 during the Resolute Hunter 26-1 exercise at the Naval Air Station in Fallon.
The goal: prepare American forces for confrontations with systems widely deployed by hostile states, including Iran, Russia, Venezuela, and Algeria.
These mock systems replicate radar behavior, electromagnetic signatures, and visual layouts of real batteries, allowing units to rehearse detection, targeting, and suppression workflows in realistic conditions.
For Iran, the implications are direct. Tehran operates improved S-300 variants such as the S-300PM-2, while also fielding locally developed Chinese-origin HQ-9–style capabilities. The Marine Corps kept details sparse, stating only that Resolute Hunter enabled units to validate emerging concepts, refine mission-critical skills, and strengthen cooperation with US partners.
