AFV units with indirect fire or: what makes a tank a tank?

From the standpoint of combat it is a "combat unit" as it has some type of firepower. So in an assault it would need to be eliminated as 1,2,3 result and not as a transporting truck. When it comes to the +1 shift for AT/AA/ART that is a grey spot. I would give them the shift because they are exposed just like a gun. With the dugin, as they are a combat unit, they can digin.
