My friends Eric and Amir came over, with Eric's copy of the latest Volko Ruhnke Counterinsurgency (COIN) title, FITL, which covers the US war in Vietnam. We walked through the programmed demonstration in the play book to learn the mechanics, they played on from there.
We had a few questions, but between the clarity of the rules and my experience with the previous COIN title Cuba Libre, we didn't find it too difficult to play. We had to stop before we were entirely played out, but the next card up would have provided a break to check victory conditions, and Eric (playing with both the VC and NVA hats on) would have won as the VC.
We all agreed that we enjoy the system and will enjoy playing both this instance and others in the future.
