This is why Iran’s Special Forces still wear US green berets
When looking at Iran's 65th Airborne Special Force Brigade, you might notice a few striking similarities — the yellow enlisted chevrons seem a lot like the the yellow chevrons on old Army greens, for example. Before the Iranian Revolution, their unit insignia looked a lot like the De Oppresso Liber crest that signifies the United States Army Special Forces.
The distinctive green beret worn by the Iranians may not be the same shade of green worn by today's U.S. Army Special Forces, but Iranian special operators wear green for a reason — they were trained by Americans.
In the 1960s, the United States sent four operational detachments of Army Special Forces operators to Iran to train the Shah's Imperial military forces. The Mobile Training Teams spent two years as Military Assistance Advisory Group Iran. Before they could even get to Iran, the soldiers had to pass the Special Forces Officer course at Fort Bragg, then learn Farsi at the Monterey, Calif. Defense Language Institute. Only then would they be shipped to Iran to train Iranian Special Forces.
It's been a long time since the 65th was a part of the Imperial Iranian Special Forces. Now called 65th NOHED Brigade (which is just a Farsi acronym for "airborne special forces"), the unit's mission is very similar to the ones the U.S. Special Forces trained them for in the 1960s. They perform hostage rescue, psychological operations, irregular warfare, and train for counter-terrorism missions both in and outside of the Islamic Republic.
Inside the Iranian military, the unit is known as the "powerful ghosts." The nickname stems from a mission given to the 65th in the mid-1990s. They were tasked to take buildings around Tehran from the regular military – and were able to do it in under two hours.
Since their initial standup with U.S. Special Forces, Iran's 65th Airborne Special Force Brigade survived the 1979 Iranian Revolution, then they survived the brutal Iran-Iraq War in the 1980s, and now advise the Iranian Revolutionary Guard Corps as they fight for the Iran-dominated Assad regime in Syria against a fractured rebellion.

The legacy of the harsh but thorough training with American Green Berets continues in Iran. The current training includes endurance and survival in desert, jungle, and mountain warfare, among other schools, like parachute and freefall training, just like their erstwhile American allies taught so long ago.
