This class includes Hover APCs (two types) and Missle Tank.
Only the Missle Tank contains its own weapon platform. It is quite hard to deal with it, because it has high fire rate. You can destroy it with Ion Mines and Plasma Lances or Launchers.
APCs can be found in on-road and flying versions. As they are military vehicles, you will usually find Adversaries with lasers inside. If you can get one for you, this may be a big help during the mission.
These are usually road vehicles, but there are also flying version. They are civilian vehicles, but Unguided seems to like them - you will often find Unguided groups aproaching in these bikes.
What is on the sea is basically not your concern in Syndicate Wars. Boats won't fire or bother you in any way. They may be docked in port, or be on the move, but they never affects your mission.
Besides, there is no way to board them.
You'll find many of them on the city streets. Usually used by civilians, but sometimes also by other groups.
Taking them down with minigun or laser requires some time, so better use Launchers or Ion Mine. Yes, one Ion Mine should be enough.
Emergency vehicles have better armor than civilian ones. They include two police cars, ambulance and fire car.
Police Cars are usually occupied by Police. It is quite hard to get oficers out of the car, so you will probably have to destroy it. I recommend dealing with them before mission, because if they'll engage you during other task, you may have large problem. There are flying versions of both Police Cars.
Ambulances usually carry civilians or scientists. If this is the second case, don't forget to persuade them at end of the mission - the more scientists you have, the better.
Fire cars are quite rare, and always occupied by civilians.
These are usually in Zealots hands. First one is similar to tank (also carries missle platform), second is probably unfinished, and therefore never used in battle (you will see it, but there will be no way to board it).
These are just civilian vehicles, but sometimes used by other fractions. The taxi vehicles have flying versions.
Space shuttle is quite rare vehicle. It won't allow you to fly into space during mission, and it is too large to use it on a mission, so you won't make any use of these. They are only in flying version.
The trains are heavily armored, and can only move on rails. You will find them useful on some missions, especially because AI is not able to use them.
First of these is the favourite Zealot vehicle, the two other are civilian vehicles. All of them can be found in flying versions.
