Damage tanks, let your friends get the kill.
Every week World of Tanks developer Wargaming gives their players special challenges to complete called Operations. This week is Operation: Confederate, which tasks players to shoot enemy vehicles that must then be destroyed by another player.
Operation: Confederate is a team Operation, and you'll have to work with your allies to earn the Confederate achievement. To get the achievement, you have to hit at least six or more enemy vehicles than any other player on your team. If at least two or more of those vehicles are destroyed by another player, you'll earn the achievement...if you're the player who earned more XP in battle.
Additionally, players will net 750 bonus experience every time they manage to set up more kills than any other ally on the team.
The event is going on now and ends at 7 A.M. EDT on June 28.
