The Army has a WOFT program... but that's for rotorwing and warrant officers, however it's mostly direct in, I'm not sure of the specific, but from what I've heard they are hurting for rotorwing pilots. As far as the Air Guard goes if were in ROTC and have a DD785 you are generally not eligible for any flying positions. If you do get into the guard it goes AMS for 6 weeks, then onto UPT. From what I've heard they take mostly their own, however if they like you, you may slip into a slot.
The Army is the easiest bet though. I'm not sure how fixed wing slots open up, but I have heard they are usually given to 4 year degree holders via ROTC.
