In fact, the very nature of that portion of the training was "we don't normally play the ATO/joint tasking game. But we understand we have to make nice with everyone else on the playground for deep strike." So, things change. But usually it involves more capabilities, and more mission sets due to improvements in technology, increased multimission platforms and fewer assets.
In the case of the Army playing in the larger aerial campaigns of the recent past and the present, things haven’t changed that much at all. They still largely provide direct support to their forces and that is about it. As for more capabilities, the Army doesn't bring that much more in the way of capabilities than the other services already have, so what is the point? I seriously doubt that changes anytime soon with our current budget environment and the Army's attitude toward it's aircraft and aviators as just another branch like Logistics, Armor and MPs.
