What ranks could we realistically do away with that has the least impact ot the force structure?

CW4 (Join to see) I'm not sure I agree with removing any ranks. I'm more of an ADD ranks kind of guy. The Warrant Officer Corps made a CW5 rank to retain senior aviators which are worth more than ome branches realize. They guide senior leadership in ways that no service academy could ever teach. I believe there should be an E-10 rank for those CSM's who get to the brigade level. I'm not sure if that would help some CSM's realize that they might be best served retiring or not. I'm the opposite of a staff guy. I also think that certain technical fields such as avionics, aviation, & certain fields that have lengthy AIT's should return to the specialist ranks. Patton was one hell of a General, but if he was working on SCAS issues on my helicopters, I wouldn't want them hovering over any of my RallyPoint family.
