It's definitely propaganda, but it's still indicative of the fact that there are units with a high-degree of small-unit tactics.
Also, if you remember back a few months, these are the same guys who were instructors for the Basij, which for me indicates that not only are they regular SF/airborne troops, but they're also meant to maintain and act as a force-multiplier for guerrilla insurgencies. For instance, if Iran ever get's invaded, 1 company(or whatever) of these guys integrated with 1 battalion of Basij would have a far greater impact then 1 battalion of Basij off doing their thing and 1 company of these Pasdars off doing their thing.
At least that's how i interpret it.
