Missile among dangerous cudgels (4)
I believe the answer is:
scud
'missile' is the definition.
(type of long-range missile)
'among dangerous cudgels' is the wordplay.
'among' indicates a hidden word.
'SCUD' is hidden in the letters of 'dangerous cudgels'.
(Other definitions for scud that I've seen before include "Traverse swiftly" , "Hurry along (like clouds)" , "Russian ballistic missile" , "Skim along; Russian missile" , "fly" .)
