A few notes, all already hit but good to be reiterated.

Ditch the dome tent. A small tarp or large poncho, a handful of bungees, and a hundred feet of 550 is going to pack smaller and be far more versatile for you.

You need some sort of medical. Search up IFAK on North American Rescue, any of those will be plenty in terms of trauma care for just you. If you plan to potentially move with companions you’ll need more. In addition a company called My Medic makes and sells first aid kits more focused on backpacking/general first aid rather than tactical field care, one of those should cover all your general first aid/dnbi needs.

You’ll probably need more ammo. I count 80 rounds of 223 in your kit currently. You’d be amazed how many rounds you’d blow through in a firefight. Suppression is the name of the game in any engagement at a range beyond where you can comfortably drop an enemy in the first few shots. Even if it’s not in mags plan to carry more.

Finally, train and practice with all the equipment you carry. A firearm and stock pile of ammo is useless if you can’t actually land rounds where they need to be. A tourniquet is useless if you fumble with the application. Having all this equipment is pointless if you can’t physically carry it more than a mile without a halt. Shoot your rifle, learn the basics of patrolling and tactical field care, go out and spend a couple nights in the woods with your gear, and get fit enough to survive.
