Movement Types?

[Trifler]

Is there any information available on the effects of the different movement types? I checked the manual, but I couldn't find information on this.

For example:
Leg
Towed
Wheeled
All Terrain
Half-Track
Tracked

I'm pretty sure it goes: Towed < Leg < Wheeled < All Terrain < Half-Track < Tracked, but how is each affected by different terrain, etc?

I'm particularly interested in a comparison between Wheeled, Half-Tracked, and Tracked.
