Equipment needs

[LordOfWar16]

If you add 1 motorized battalion to a division it wont move any faster. The rest of the division still is on foot, i,e the motorized brigade has to wait. Support Companies already reflect the need for trucks, since a regular division has support companies attatched to it, which will need support equipment and trucks etc.

 

[Bridger15]

Earlier Hearts of Iron games represented this gradual introduction of trucks into infantry divisions by slightly raising infantry speed as the tech level rose, and adding fuel consumption.

And, as others have pointed out, HOI4 does this with Support Companies. The Support Artillery you add to your division does *not* lower the speed of the division because it comes with it's own trucks.
