Hunt enemy welcoming scrap (6)
I believe the answer is:
forage
'hunt' is the definition.
(I know that forage is a type of hunt)
'enemy welcoming scrap' is the wordplay.
'enemy' becomes 'foe' (foe can mean an enemy or rival).
'welcoming' indicates putting letters inside (in sense of 'inviting in').
'scrap' becomes 'rag' (both can mean a piece of material).
'foe' going around 'rag' is 'FORAGE'.
(Other definitions for forage that I've seen before include "Rummage, search for" , "Rummage, go searching" , "look around" , "Military raid" , "Search around for food" .)
