Just restarted my Old Man playthrough on #Arma3 and holy crap I'm not sure if I'm overthinking it or that scenario's designed to make you paranoid.
@BalooUriza Can't say I remember, but it can't have been more than 10. At one point you may or may not find something to speed it all up, like a heavily armed car or a helicopter, so your experience might be different.
I'm not sure how far you've gotten and don't want to spoil anything, but I've ignored some quests because, as you said, I was pretty paranoid when dealing with some people there.
