Also aim to capture the soldiers (7)
I believe the answer is:
platoon
'soldiers' is the definition.
(group of soldiers)
'also aim to capture' is the wordplay.
'also' becomes 'too' (synonyms).
'aim' becomes 'plan' (I've seen this before).
'to capture' indicates putting letters inside.
'too' put inside 'plan' is 'PLATOON'.
'the' acts as a link.
(Other definitions for platoon that I've seen before include "Group under lieutenant" , "Small military unit" , "Small body of soldiers" , "Army unit" , "Division of company" .)
