Seeing the suggestions here gives me some pause.
The SRA is a fine entry organization. Join that. Shut the fuck up about sectarian issues, make some friends.
Buy a 9mm Glock and an AR 15 chambered in .556.
Next you need to start training. Local range for paper static targets. Dry fire.
Try the dry fire drills.
After that, start learning shoot and move drills. At this point you need a belt, holster, plate carrier, level 4 plate, ifak and radio (baofeng).
You need friends. There are going to be local groups in major cities. They're not going to have a Twitter. You are going to need to wear patches at competitions or start making face to face friends.
At this point you're better trained than the fucking feds fucking around.
I have seen nothing from DSA or PSL that is remotely ready for what I think comes next.
NB: one untrained person with an AR 15 scared the shit out of all the cops at Uvalde.
There is no de-escalation coming from this regime and there is nothing the dems are going to do. Trump could dissolve Congress and we'll get some angry letters in response. If you think you can run to anywhere but China, I think we'll all find that Canada and Mexico are not safe.
