Every time they showed a 500 lb bomb be used in the mid east to take out a pickup truck or some other type of ground vehicle I kept wondering where are the A10s that could do that job at probably 1/10th the cost.
You’ve just put your finger on one of the problems. The A-10 has legendary loiter capabilities, but it isn’t what they would call a “fast mover”.
The standoff capability may have something to do with it. The fighter-bomber can target that vehicle from miles away without them knowing they are being watched. They'll never see it coming. BOOM! The A-10 is a frightening sight but can be seen well before it makes its attack run. Gives the bad guys time to abandon the vehicle and seek cover.
