Ah the joys of public...
Normal public response
"Oh whats that? A tank that just killed me, oh ok i'll respawn as Medic again" *10 seconds after spawning* "Omfg the tank killed me again, respawns as Medic" *Calls the driver a tank noob* "Gets killed again" *rages at both the tank noob and his team for being noobs*
Response from someone who isn't a moron
"Damn tank" *spawns as Engineer with RPG/AT4 and MK2 explosives or Assault/Recon with C4 or Recon with Mortar if its too far away and proceeds to blow up the tank* (optional ending, "I need help with this tank, its getting repaired too fast" *3 more missiles join the fray and it goes bye bye"), possibly followed by "Better chuck some AT Mines down just incase".
