Here's something I did to help me learn about the town.
In offline mode, take off from the airfield. Fly over the town, and bail out. Now pull out the map for the town, and go for a walk. Press W for walk, and R for run. Explore the town for a while. Go to where the flag is, and you will find the map room (It's underground).
The next time I was online, when it came time capture a town, I had a much better idea of what was going on.
To make it more interesting, last weekend I explored the town at an enemy base. I flew over and dropped a bomb in the middle of town. Then I spent some time de-acking the town. Then I bailed out, and took a walk around the town. This gave me a good chance to see how much damage a 1K bomb does.
