Army commitment is 6 years Active Duty after flight school. There is a "Highschool to flight school" program where 18 year olds can (if qualified) go from Basic Training direct to Warrant Officer Candidate School and then to Flight School. If you want to fly in the army then you don't want to be a Branch Officer (ie. LT, CPT, MAJ etc.) because the desk and managerial/leadership responsibilities get in the way too often.

Airliners.net has millions of great photos and a great photo search function, several good videos on youtube if you search airline pilot to get a "Day in the life."
