Russian "Advisor" Company. The rules, of course, contain no OOB for this unit, as they didn't exist. I couldn't help adding them in, however. I worked in Korea for a while, where it was a bit of a standing joke with the older guys.
1950s PLA. One of the assault companies, and on the right a weapons company. I had to do a few head swaps on some Russians to make up the numbers but happily the sets come with several casualty figures so there's a few spare anyway.
