Tanks for each soldier initially without a country (7)
I believe the answer is:
panzers
'tanks' is the definition.
(panzer is a kind of tank)
'each soldier initially without a country' is the wordplay.
'each' becomes 'per' ().
'initially' suggests taking the first letters.
'without' is an insertion indicator ('without' can be similar in meaning to 'outside').
'country' becomes 'nz' (abbreviation for New Zealand).
The initial letter of 'soldier' is 's'.
'per'+'s'='pers'
'a'+'nz'='anz'
'pers' placed around 'anz' is 'PANZERS'.
'for' is the link.
(Other definitions for panzers that I've seen before include "German tanks" , "Armoured combat vehicles" .)
