I have seen tanks and vehicles do what you refer to.Bieng partially in a building.But what i saw was a tank,controlled by the ai drive straight through a building,not skirt around it but right through.I was on trench cam directly in front of the tank as it emergred from the middle of the building.I do not have it on one of the magnified settings.Is this a glitch?Is it my cpu?Or a special ai only secret weapon.Like laser guided mg bullets in close combat?
