Edit: The Planetside 2 Elite Soldier Bundle is sweet!
You spawn as an infiltrator. You steath into the enemy base, pull off some solid snake bs, nobody sees you. Exposions all around panic everywhere. You hack the enemy base turret and start blowing up the enemy with thier own defences. Suddenly! You explode!
Ahhh darn they got you! but wait! You were teamkilled by a rank 1 NC Heavy on Connery named asdfghjkl.
At first your mad, but then it dawns on you that he is actually... A tactical genius! He knew that you were gonna die anyways, so he denied the enemy points. By shooting his rocket at the stationary base defense, instead of those small hard to hit infintry scattered around the ground. He insured something was getting done while denying an extreme menace kill to the enemy.
On NC Connery every teamkill has a tactical significance no matter how big or how small. They had your best intrest in mind when they shot you in the face.
