APC or not ?

[leonard]

What do you think of the status of Kubelwagens, Jeep MG or Soviet KMS regarding stacking and casualties (X obtained on Bombardment table for example) ?

Kubelwagens and Jeep MG are combat units AND transports but no APC.
Soviet KMC is a combat unit AND transport (Prime mover) but no APC.

Stacking limits are 
- 3 combat units
- 3 transports (incl. APCs) + passengers/guns in tow

Bombardment casualties :
If X, one combat unit loses one step (not close top AFVs) AND one non-APC transport lose one step, too.

Do you treat these units as APCs even if they are not ?
