I was an army commissioned aviator for 7 years. Much like these guys say, the warrant officers do most of the flying. As a commissioned guy, you'll fill the leadership roles of platoon leader, company commander, battalion commander. You'll also get more than ample opportunity to serve in staff positions such as personnel officer, logistics officer, operations officer, intelligence officer - in other words, jobs for which you have had and will not get training, thankless jobs, and while in these jobs, if you get to go fly once a month you're doing well.
Of my 6 years in line units, I spent 2 years as a platoon leader and 4 years as a staff officer. If I had stayed in, I would have commanded, probably only for 18 months, and then it would have been off to another series of staff jobs for the next 5-6 years.
Bottom line - if you want to fly, go warrant or go another service.
