|>> || A Mosin-Nagant and a 1911 are probably the most robust choices of firearms. |
A Bowie or K-bar for the knife, unless you can get a Tom Brown Tracker.
Studies of survivors' stories from countries that went to shit suddenly, suggest that the best option is to network with people, relatives, neighbours, friends, to protect each other, and organise food, water, shelter, and medicine. Mobile, armed loners get shot at roadblocks, and retreaters are burnt out by military, police, gangs or mobs and killed. Heading innawoods sounds attractive, but you'd better have proven, working and functional skills at camping, fishing, hunting, crafting, first aid, herbalism, orienteering, etc to actually be able to subsist off the land indefinitely. The absolute worst thing you can do is be just another refugee.
For training, I'd suggest the classic military CQC styles, Defendo, Combato, Defendu, Mosche Feldenkrais ju-jitsu, Paul Vunak's Rapid Assault Tactics, not the modern junk. Native American tracking, the stuff that includes knife fighting. SCA-style "historical Ninjutsu", the kind Christa Jacobsen and Anthony Cummings were developing before they all turned on each other, none of that silly Bujinkan waffle. The old Marine LINE system, not the MCMAP watered-down UFC rubbish they replaced it with. No S.C.A.R.S., it's rubbish. "Autokinetonics", PFUI! That's some Remo The Destroyer-level bullshit. Krav Maga and Systema are too unregulated and adulterated to be dependable these days, there's lot of piffle being sold under those brands.
Give some thought to improvised weapons, e-tools, tent poles, hatchets, machetes.
