Here is a listing of the packs available - do note that there are not enough horse packs to match to the cavalry packs (might still turn up in the great mass of stuff being waded through). Seems enough to put together quite a nice Russian Revolution setup. And, if Frontline Gaming is still trading, plenty of options to expand as needed/desired.

And, as an aside, if Frontline is still trading the full range, there is rather a nice selection of German East Africa figures for anyone so interested. (I have my GEA in 15 mm from QRF). And, nothing on the list above, just thought I'd mention.
