It depends what the theater of operations is and what is it’s intended duties. I’m sure in certain cases it could work, but it can’t go head to head with jets. It’d be hit before it ever saw them coming.
And what good is the Eurofighter or the F-22 in Afghanistan? I don't think anyone was suggesting scrapping jets and going to Tucanos. But cutting back purchases of one platform that is useless in your current combat environment in favor another platform that is perfect for that environment makes sense in times of finite military budgets. The U.S. Air Force should be so smart.
