Artillery Expert - Achievement - World of Warcraft
Artillery Veteran - Achievement - World of Warcraft
These achievements require you to destroy vehicles using a turret. Currently, as long as you're sitting inside one, you get points towards the achievement whenever a demolisher is destroyed, no matter how far you are from the kill (or if there is a range, it is considerably larger than the range for honor gain) and you don't need to deal any damage to it either.
The best spot is the middle line. Try to guess which side the opposing faction will be coming from and hide on a turret on the opposite side (marked with a big red dot on the map). If they come your way, act as if you weren't there (don't move the turret and don't shoot) to increase your chances of not being noticed and killed. A bad match will net you about 6 kills, a good one even more (depends on how many demolishers are destroyed).
