I've myself lost turret sometimes to somewhat tiny shots which went all over by the enemy from far far off..
perhaps ping or two heard and turret dead as well as the enemy.
then theres been times when turret has kept alive through few passes.
Same thing has happend to me against ostwinds..
Sometimes I get turret no problem or whole thing blows up with rockets, but sometimes I get multiple direct hits with rockets and strafe for a bonus, but Ostwind *still* keeps firing.. although, without tracks.
