For me, personally, joining a group and 'going on the offensive' as one poster put it, wouldn't be an option worth considering. The best response,
I think, would be to make yourself an unattractive target in as many ways possible, and reduce your visibility to the greatest degree possible.
That means no hanging out with the rebel militia.
Those guys stand 0 chance, given the amount of firepower that can be brought to bear on the modern battlefield. A high percentage of marines would
fire on their own citizens if commanded to do so. That's the reality we live in now. Unless your local militia is in posession of some artillery
I would prefer to remain small and insignificant, taking care of myself and my family using a micro farm, foraging, and hunting.
The list given earlier was a good one, a bit heavy, but I have one particular suggestion. Drop the big axe. A camp axe is perfectly suitable for
everything but felling sizable trees, and you should really never need to fell a sizable tree.
Small axes let you chop saplings and small lumber, split, and plane. A pocketknife with a couple of sturdy blades does the small stuff, like
whittling, and you're set (unless you plan to hunt large game, in which case you'll need a faster way to dress them - a tanto [chisel point] with a
gut hook on the back of the blade would be ideal). No good reason to add eight or ten pounds to a pack for no solid reason. You'd be better off
filling that space with .22 rounds for use or barter.
My firearm of choice in a situation like the one you listed would be the springfield survival rifle. It's quite rugged but also lightweight, fires
both .22 LR and 40 gauge shot shells, it's easy to maintain and clean, and it shoots straight.
Not much use for taking on the army, but it's worth its weight in gold for bringing down game.
In addition to your list, I would reccomend snare wire, some whisky, cigarettes, and maybe an ounce or two of gold shot (tiny beads of gold made by
dripping molten metal onto metal ramps submerged in water), and a few yards of parachute fabric. The first and last items (wire and fabric) are
invaluable in survival situations, for trapping and shelter-building respectively, and the three in the middle (smokes, booze, gold) are invaluable
I would reccomend the shot over buillon forms, simply because it's easier to carry and trade than a great whopping brick or something like that.
