I stalk tanks a lot. I could earn more Xp doing other things, but I find it fun. I will spend 10 minutes follwoing a tank around if I have to. I will also sit at random locations that I know a vehicle will be passing through and wait with C4 on the ground. (there are also tank mines out there somewhere) I have a lot of clip of video of me C4 camping spots from trees, rocks, and even hiding in bushes.
