… soldiers run to be caught by police (5)
I believe the answer is:
corps
'soldiers' is the definition.
(a group of soldiers)
'run to be caught by police' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'to be caught by' indicates putting letters inside.
'police' becomes 'cops' (cop can informally mean a police officer).
'r' placed within 'cops' is 'CORPS'.
(Other definitions for corps that I've seen before include "army band" , "Body of men" , "fighting group" , "Army unit" , "ballet group" .)
