I didn’t say this in my other comment, but it’s important enough to be its own:
If you think you’re going to be targeted, use the buddy system. Don’t go anywhere alone, for any reason, ever. One person is an easy target, two and especially three people are a lot harder to deal with.
Physical maps are fine, but take some practice to actually use well. I wouldn’t pack transmission radios like walkies- most that are affordable are unencrypted, and the encrypted ones are in all likelihood already broken by the alphabet gang. Plus, they need batteries and they’re just not that useful in practice, imo. An AM/FM receiver, though, I could get behind that.
