Regularly orders prompt salvage (6)
I believe the answer is:
rescue
'salvage' is the definition.
(I know that salvage is a kind of rescue)
'regularly orders prompt' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'prompt' becomes 'cue' (cue can mean a prompt or signal).
The alternating letters of 'orders' are 'res'.
'res'+'cue'='RESCUE'
(Other definitions for rescue that I've seen before include "Salvage" , "delivery" , "Save from peril" , "Set free from harm and evil" , "Extricate" .)
