Well, I guess its really 2 different roles of 2 highly capable
tank busters.
The A-10 is really well suited for its role of Close Air Support,
staying on Station, raining Mavericks, Cluster bombs and 30mm DU
rounds from above.
But when u really need to plug a gap, slow down an advancing
armored column, ambushes. Zip to the where the enemy is, loose more
than a dozen hellfires on the vehicles while hovering behind a
mound, or even below tree top level. Not much u can do unless u've
got some air support to flush the choppers out.
Even so, apache's can be armed with Sidewinders... JUST IN CASE.
