Retrofitted. Basically, in reading the comments at the various websites, some posters are saying these are leftover vehicles from Iraq and Afghanistan and are being upgraded so they don't rot.
These are NOT new purchases as implied by the headline. Which calls into question some of the other claims. I would take this reporting with a grain of salt. Let's get some more facts before leaping to conclusions.
If they were being stored they would not have DHS or cop markings. They would be stored at a base somewhere. The AF has storage of war ready materials at each base. These are brand new equipment that is not used for daily operations.
