Haha there was a time when an enemy tank came into the edge of the base, I decided to shoot a smoke grenade in front of it to make it harder to see. I equip my smoke launcher, aimed and when I pressed the trigger my team medic went right into the line of fire (he was shooting at the tank with his gun >.<). Suffice to say he died from the impact.

He respawned on top of me and while I was shooting at tangoes, he took out his pistol and shot me from behind till I died. DOH!
