Few questions

[PRECISION]

I finally got this game today, and I'm loving it, but I have a few questions.

In my campaign, I'm on a mission where I have to check out three towns, and each one is very far away, especially by car transport. So is there any way I can call in a chopper to pick me up? Or get one to fly myself?

And my other question is, how do I unlock new vehicles in the armory?

-Thanks.

You cannot fly choppers yourself in Harvest Red campaign.

No idea how to unlock vehicles in the armory, my best guess would be that maybe they are unlocked when you meet them in the missions, but someone else may reply that as a fact.
