With the recent release of the two officiall (German and Soviet) lists for the Polish campaign 1939 I also uploaded my own (yet to be approved) lists for Polish cavalry and motorized cavalry. There are download links to all of them on my blog. The additional Polish cavalry platoons use the same support option chart as the Polish infantry platoon - but I have added notes on how what support option limits you may want to include if you want to keep the lists historical.
I also added the same type of comment for the German SS list.
Also since writing lists for this game has proven to be quite easy I may look into compiling some more lists for the 1939 Poles when I get the time.
