Rules for wars of religion/late 16th century for 15mm

[jet]

I recommend Irregular Wars as well. IMO, they are one of the best written rule sets of any genre. They are concise, there is no ambiguity, and they might be the first rules I've ever played where I never had to go online asking for clarification.

Who publishes them?  Can they be purchased?

I bought the PDF and never looked back. The author was clever I think, to create a professional black & white layout that looks fantastic printed on a regular printer and stuck in a binder.
