Should the Army have gotten rid of the OH-58D "Kiowa" Helicopter?

The OH-58D fills an important mission role. There is no other aircraft in the current inventory that fills that role. Until they have a replacement aircraft to fulfill that role, they shouldn't get rid of it. Part of the problem is that Gen Cody killed the RAH-66 Comanche program. That aircraft was purpose designed to take over the Band-Aid that the OH-58D program always was. If the 58D is mothballed (and it shouldn't be), then I foresee that the UH-72 Lakota will start sprouting extra equipment (like a mast mounted site), 2.75" rocket pods, and/or externally mounted machine guns.

I'm a firm believer in not trying to fix what isn't broken!

absolutely not that thing is awesome !!
