In the Iraq war, as most will know. The F-111 was the tank killer. The A-10 was driven out of the battlespace during Kosovo. It really is political with good "shoot em up" videos that keep the A-10 in the air. It is not survivable in a modern battlespace.
The F-111F night "tank plinking" strikes using 500 lb. GBU-12 laser-guided bombs were particularly deadly. On February 9, for example, in one night of concentrated air attacks, forty F-111F's destroyed over 100 armored vehicles. Overall, the small 66-plane F-111F force was credited with 1,500 kills of Iraqi tanks and other mechanized vehicles.
144 A-10s 900 Iraqi tanks, 2,000 other military vehicles.
