For a militia to be effective there needs to be training curriculum that is disciplined, organized, and standardized that matches or exceeds that of the opposing force if it is to succeed. It would require funding to operate and volunteer manpower by the well experienced and trained wih ranks and divisions set up for different duties.
Disagree. You’ll need cells and compartmentalizations. And plan for highly asymmetrical action.
The Michigan Patriots Association had such a training curriculum set up. They were disbanded under Federal pressure. I've reprinted some of their training material in my book RESISTANCE TO TYRANNY (yes, a shameless plug). Available from Amazon as either printed copy for for Kindle.
