ukraine '43 missing remnants

I am setting up Ukraine '43 as the Russians, but I cannot find remnant units, neither in the remnant box, scenario cards, or unit inventory. Where are they found.

Well, I have found my missing remnants. They are not separate counters, but the 2nd reduction of a given 3 step unit.

I should have known that. I have played other Simonitch games on Vassal.
