Menelaus said:You can break the laser lock if you break LOS, right?
I don't think so. I've locked onto tanks that then backed behind cover, and it didn't make a difference. Shell went right around the corner. Same with heli's and hills. If you haven't been locked onto you can break LOS and get out of it though.
Honestly I think it's one of the under used high end strategies in the game. You can make people in Heli's cry with a single tank, and all it takes is two people.
