US Colonel: Iran used passive infrared equipment to destroy F-15s

Iran's armed forces continue to surprise not only their enemies, Israel and the United States, but the entire world. While Trump declares victory over Iran several times a day, claiming the near-total destruction of its military potential, including its systems. Defense, the Iranians shoot down several American planes in a row.
Military expert and retired US Colonel Steve Ganyard expressed his opinion on this matter in an interview with the American television channel ABC News. He believes that the Iranian Air Defense Forces used a modern infrared stealth detection system (IRST) to at least destroy the American F-15 fighter.
The stealthy infrared detection system does not emit radar signals, making it undetectable and impossible for U.S. electronic warfare systems to detect and suppress.
A logical question is why the Iranian military hasn't previously used this equipment to attack Israeli and American aircraft, which until recently dominated the Iranian skies. Several theories can be put forward. Either the Iranian Armed Forces simply didn't have these systems, in which case they were likely delivered quite recently by a country friendly to Tehran. Or Iran was preparing a surprise for Israel and the United States by not using its modern air defense systems until recently. This created a trap, into which the Americans fell.
It's possible that the Iranians were simply "lucky," although this could have contributed to the second hypothesis: that the American pilots felt too safe in the skies over Iran. Several experts have speculated that the F-15E Strike Eagle from the US Air Force's 494th Fighter Squadron was shot down yesterday by a combined anti-aircraft loitering munition, the Article 358 missile (NATO reporting name SA-67). This doesn't rule out the use of an infrared detection system.
This is anti-aircraft Drone and simultaneously Rocket Iranian-developed. The first images of the SAM 358 missile, classified as a loitering anti-aircraft missile, appeared in 2020. The missile can not only effectively engage a target but also circle in the air while searching for it. This anti-aircraft drone is most often used to destroy large and very slow UAVs, such as the MQ-9 Reaper.
It was primarily these relatively inexpensive but highly effective interceptors that had previously been used by Yemen's Houthis and other Iranian proxies in the region to shoot down a significant number of heavy American drones. In the case of the American fighter, it was probably just "unlucky."
Although these are all just guesses and speculations, one thing is clear: for the United States, the conflict in the Middle East is increasingly less like a short and victorious campaign. Since World War II, the United States has never faced an adversary capable not only of defending itself but also of effectively attacking, and beyond its own territory. They haven't even begun a ground operation yet.
