It's not only mil ATC. When I started operating out of my current civilian airfield, on calling for rejoin, Approach would tell me "Join for right base 22, QNH 1000". Being a helpful chap, much like A & C, on changing to tower, I call, "Joining for right base 22, QNH 1000". Tower reply, "Join for right base 22, QNH 1000", again expecting a read back. I don't bother anymore.
And don't even ask about wake turbulence separation.
