No inclination from military to make allowance for sovereign? (5,4)
I haven't cracked this one yet — but Fifteensquared have:
DD/CD. List here is used in the sense of tilt, so non-military tilt might be a civil list. The civil list was a previous mechanism for giving money to the monarchy – it has since been replaced by the sovereign grant.

I haven't cracked this one yet — but Fifteensquared have:
Not sure about this, but possibly rip(=preserve, as in the term for making electronic copies of something on a tape, CD etc) + cord(=neck of jumper, which would be a sort of cord).
