A B-1B is at least as effective at taking out an armored advance (cluster bombs), and at CAS with JDAMs.
And is not at risk from shoulder fired missiles.
False on two counts
No A-10 has been shot down. Show the shoulder fired missiles is not a serious threat.
A A-10 30mm round costs $100
A Jdam costs $25,000 just for the assembly. then you got to buy the bomb for $12,000 each
A CBU costs $14,000 per unit.
