How to classify a unit?

[Perturabo]

A foot infantry company with 20 small light tanks. Would it be foot? Or tracked?

 

[Joe98]

There is no such thing in the game as tracked movement type

The choices are foot and wheeled.

 

[Dave 'Arjuna' O'Connor]

Moreover, the attributes of infantry and armour would best be reflected by separating out the light tanks into one unit and the infantry into another.
