When I A-move a tank, it drives about 45 meters past where it should stop and shoot. Then it blows up. Same with any vehicle. Cant kite a Kubel. It either cant "see" the enemy or does the same thing tanks do where it drives right up to the enemy before shooting. The server code is complete garbage.
I think this happens when you A-move units with a coaxial MG. The different weapon ranges between maingun and coaxial MG just totally mess up attack moving I think.
Now the real question is why people keep doing it after you noticed that A-move doesnt work on these units
