Really? All of them? Are you sure about that?

I believe there is a policy proposal in the ARIN region which, I have it on good authority
is still active.

True, it doesn't technically designate more RFC-1918, but, it does create a /10 of space
for shared use for the purpose of LSN intermediate space or other carrier-level private
network usage.

In this case, the block has been allocated yet doesn't appear to be in the routing system and I'm not sure it ever has been (at least authorized to be).  I'm guessing Rogers is making the assumption that the chances are probably small that one of their customers will need to communicate with a non-announced US DoD network.  I suspect they aren't the first to make this assumption.

More likely they are making the assumption that their private internal use of the address
space won't conflict with DoD's (apparently) private internal use of the address space.
