The ones comitted to Afghan ops don't have hoses. The other six do!
And 4 of those 6 have certain other bits of kit fitted that are nothing to do with AAR. As a result they are heavily committed to the AT support of both theatres. There is virtually nothing left to be squeezed out of this particular fleet.
It would take the fitting of a buddy-pod to Typhoon for those at the top to be interested in AAR.
