Antistasi Ultimate help

Hello revolutioners!

I am new to Antistasi Ultimate version (I have hundreds of hours in Plus version), and I have some question about some features.

• Civilian Convoy. What does it means? I see some civ vehicle whixh is going somwhere. They are "reinforcement" to grow the population of a city, or what does it means actually?

• Politics. I knew people who to like or dislike but what does it means about government support?

• Base buildig. Is there a way to create new outpost, stronging roadblocks or just an easier way to "decorate" and make bases more effectively?
