The french Sherman 105 has an issue where when moving forwards at a decent pace the front of the treads begins to sink into the ground, stopping will cause the treads to pop back out of the ground, but it happens any time you’re moving forwards at speed.
This happens reliably every time in a ground mission, at least definitely in realistic battles, aside from being a graphical issue this also affects handling, having part of the tank in the ground seems to cause it to be laterally unstable and roll side to side, this effect is worst when you stop, as the sudden jolt of the tank treads popping back out of the ground causes the turret to move wildly, leading to cases where you stop to line up a shot, and just as you would shoot the aiming reticule pings off into the air.
This has happened reliably every time I use the french 105 sherman in a realistic battle, not sure if it affects the other sherman 105s or if it’s a weird kink specific to the french one
