I have zero faith that they will get to giving the Reserves useful stuff before the money taps get shutoff. Plus if they bought K9's for the Reserves, they would be broken down for most of their lives as there will not be enough maintainers and many will have to sit outside as they won't fit into many of the armouries.
Believe me I deeply hope I am wrong and well supported modern equipment flows to the Reserves. But my gut says I am right. Plus you don't have a lot of time before the current fleet says "We are done".
