Why wouldn't a 1000lb JDAM have any capability against armor? If it isn't moving, it seems like a JDAM would be the perfect weapon.
1,000 pound bombs can take out large buildings, you don't need to waste that expensive a weapon on a tank!!! This war would cost trillions and trillions if you needed to use ordnance like that on a tank. A simple Hellfire missile will do -- and they did, to the tune of 70 enemy tanks. There won't be enough punch left in that Division to stop a troop of boyscouts after that engagement.
