I'm not sure where the idea that the Army doesn't have runways came from. Almost all Army posts have them. It's how we get their equipment to theater... C-17 to Army Airfield, then head out to theater.

The Army also has a sizeable fleet of fixed wing aircraft already.

I have my opinions about the Army (read: infantry mafia) generals effectively employing armed fixed wing assets, but that's a different discussion.

Intellectual honesty is the most important character trait in human beings.
