An AK and a pistol in .45 or 9mm and a lot of ammo.
First aid kit. MREs, canned food. A lot of water. Gasoline. Maps of your area and surrounding areas. Compass. Binoculars. A good load bearing pack. Field mess kit. Good boots broken in. Two sets of sturdy clothes, skivvies, socks, field jacket (depends on climate). A book on Wild food identification. A good set of tools. A whole bunch of common sense.
It'll take you a while to have everything. Buy over time.
