While I was looking for video clips on youtube about green berets, ( I know the proper term is The Quiet Professionals, which in many ways is true. )
I was really surprised, even though I know part of special operations' job is training foreign armies to be able to defend themselves, long after the Quiet Professionals leave.
I came across this video clip from the early 1960's and I thought that was very interesting because it does show we had better relations with Iran.
The hand to hand combat demonstration is worth a look.
