I noticed of late when I am in an Ostwind and I get tracked half of the vehicle seems to go underground.
Tonight on Baltic map at A-29 an Ostwind was sitting on the ground near the shore batt. I shot out his turret then drove over and tracked him. The Ostwind did what I thought it would do it was half underground. Shot off the other track and he fell through the ground and was inside the shore batt mound.
