Is there a cheat sheet out there that lists the types of leaders and their hierarchy for each country? I know the supplement books sometimes have the leader hierarchies for the country/service the book covers, but it would be nice to have all of them in one place for quick reference. Thanks.
None that I know of. It is all pretty much as you have noted, in the scenario books.
It's not a big deal for most scenarios, but when one is playing a scenario pitting Slovaks against Hungarians, it's nice to have a handy reference to know how one should organize their leaders. I put together a spreadsheet with the leadership hierarchy for every country I could think of, as well as those for separate organizations within a given country, such as German SS units, Japanese SNLF units, etc. I can never remember how those SS leaders are organized.
