I will look more into ROTC for sure. I have heard a fair bit about the Michigan Militia and know what you mean by lefties talking like they know everything about it and others like them. At my campus, I have a class on government, and I see a lot of lefties in there talking like they know everything about guns and militias when the topic arises, but if you question them on anything they freeze up!
A senior thesis on a topic about militias would be interesting and now is something I need to heavily consider. It's still a while away but I will look into it more. Thanks for this!
