A very easy way to get this is to go into a survival match online where A tank comes out almost every 2 minutes. When the match starts and you have time to get weapons and equipment before you start the game grab a bile bomb (almost all levels have one at the starting point). From there just survive, wait 1:30-2:00 minutes for a tank to show up, let it go for a teammate (so it's distracted) then READY AIM FIRE the Bile Bomb at the tank. Achievement unlocked
