For those building insurgency missions, do civilians actually get recruited/ people gather weapons, or pick up ied equipment at the relevant depots or are they just there for show?

I'd love to actually see the civilians take up arms against us but they seem to just live near the recruitment depots.

Also, do civilians arm themselves and randomly pull weapons on you when you are at high hostility? I'm sure Ive seen it but want to make sure.

They will throw rocks at you...at least that much.

They most certainly do pull weapons on you, but not really on mass that I've seen.
