Motorized: Mounted vs On Foot ?

[MisterMark]

I think you have summed up the advantages/disadvantages very well, the only other factor that I can think of is if infantry in hard halftracks (i.e. a hard target) dismount, then they can be targeted by soft firepower values.

The fact that in these games there are hard halftracks and soft halftrack units is not always well understood.

Oh I wasn't aware of both soft and hard halftracks... How can you tell?  Is that something that is set by the scenario designer/OOB?
