1. Don´t know what "OBE" means, but if you think that we´ll be done with IEDs anytime real soon you´ll find plenty of people to disagree with you. I´m not saying that we won´t defeat the insurgency (I´m confident we will), just that we´ll be dealing with IEDs for a long time. All it takes is a few fanatics and a few pounds of explosives...
2. I assume that the OV-10 can loiter for much longer than either a helo or fast mover, though I could be wrong (it happened once before

).
I do agree that this seems far-fetched. Aren´t there much more pressing priorities with respect to airframe procurement (JSF, V-22, F-22, AH-1Z, UH-1Y, gold Daytons for Brett´s Prowler, MMA, etc.)?
