Where do I sign up?

I am retired military. I used to love this country, but the America I knew no longer exists. I am ready to help in assisting the revolt against the Imperial American Empire. How does one go about finding a militia group or organization ready to make a difference? Not interested in any white supremacy or anything like that - just people like me who have had their fill of this government. What I would most like to see is a group with the fortitude to annex a portion of land away from the Empire with the intent of defending that territory to the end.
