This may sound stupid, but I can't figure out how to select weapons before starting a mission. I have lots of weapons but I can't seem to figure out how to view what I have & then select a weapon to fill one of the 4 slots. Guess I'm slow.
It's called *equip weapon* (vending machine) and there are plenty of FC3 tutorials on the Internet.
the equipped weapons (assigned to holster slot) then are on the weapon dial (numeric keys in game).
