Relic has been constantly updating Company of Heroes 2 to improve the multiplayer experience, and the December patch improves vehicle pathfinding.
As detailed in the video below, previously tanks would pivot before moving a short distance. Now, that has been changed. Instead when being told to travel a short distance tanks will automatically be put into reverse to move backwards. This is only for a certain proximity, as long range reversals will still need to use the manual reverse command if you don’t want the vulnerable parts of your tank open to attack.
