On Miteirya Ridge on EL Alamein, axis gets a moveable PaK 38 when they hold the flag. The day before yesterday I was in that PaK, slowly advancing forward from its spawning position, in western direction. Suddenly the PaK started to accelerate and I rocketed over the ridge until I got stuck behind an obstacle (can't remember which one). This happened several times to me, also one time when I tried a more soutwestern direction. This is very undesirable, as you are trying to aim for enemy tanks with that PaK and all of a sudden it starts to race towards it. I can't really show this in a screenshot, as it is about movement, but it sure is annoying.
