I son5 see how selling a couple of second hand airframes, stripped of their mission equipment, is a major policy change of policy.
The reported reason they were being scrapped is that, with all the various holes and airframe modifications, it was cheaper for a purchaser to buy new rather than repair. If the US Army think they can fit new kit in them as is and have offered more than the scrap value then, from a disposal point of view, it’s a win-win situation.
Whether the role fulfilled was essential, can be better filled using another existing platform, can be gapped etc, is a separate argument.
