For all of the bubbas out there counting in c17 replacement airframes had better get a good count of the ones already in the mix. 222 was already the buy. There are no extras. Which unit that already has C17s is going to give them up to replace your C5As or Herks? Better stand up a light a match for the tails you currently have because this looks like an easy way for Big Blue to have a BRAC without having a BRAC. In other words, we're taking your jets but we don't have anything else for you.
Specifically, for those C5A units out there that has leadership BSing folks about the possibility of inbound C17s, follow the money. The bases that are getting them have already been announced and POMd.
The numbers don't add up. Protect yourselves.
