Foot soldiers shot after home supporter (8)
I believe the answer is:
infantry
'foot' is the definition.
(I've seen this before)
'soldiers shot after home supporter' is the wordplay.
'soldiers shot' becomes 'try' (I can't justify this - if you can you should give a lot more credence to this answer).
'after' says to put letters next to each other.
'home' becomes 'in' ('he's home' can mean 'he's in').
'supporter' becomes 'fan' (fan is a kind of supporter).
'in'+'fan'='infan'
'try' after 'infan' is 'INFANTRY'.
Can you help me to learn more?
(Other definitions for infantry that I've seen before include "part of the army" , "Troops" , "Unmounted fighters" , "Men fighting" , "fighting group" .)
