When you are talking about the Iranian Revolutionary Guard, you are talking about the Iranian Military. There is no difference between Military and Paramilitary in that instance. It is a branch of their Armed forces, just as the Marine Corps is a branch of the US Armed Forces.
And because the Revolutionary Guard is tasked with more political targets, it is not much different than the SS or Waffen-SS in Third Reich era Germany.
Would you so easily dismiss this if it was say the SS being sent into Holland? That because it was Waffen-SS and not the Wehrmacht?
This is what I am finding so funny, so many are trying really hard to make some kind of false connection. Iran has no "Regular Forces" is just semantics. If we sent large numbers of Green Berets and Navy SEALs in, they also would not be "Regular Forces". But nobody would be trying to deny we had military forces involved.
