Army doesn’t like fixed-wing aircraft... rotors are their flavor...
As I understand it, that "rotary wing" requirement was forced on the Army by the AF. I just finished an email conversation with the hubby of a gal I graduated HS. He retired from the Army air wing with 5000 hours flying time, only 1200 of which was rotary.
I understand the limitations of the A-10 wrt carrier usage, but the Army has no such limitations. Give the A-10's to the Army, and with it the ground support role. The AF doesn't really want it, and the ground troops need it.
