Section ready to house good soldiers (7)
I believe the answer is:
segment
'section' is the definition.
('segment' can be a synonym of 'section')
'ready to house good soldiers' is the wordplay.
'ready' becomes 'set' ('set' can be similar in meaning to 'ready'**).
'to house' is an insertion indicator.
'good' becomes 'g' (abbreviation).
'soldiers' becomes 'men' (I've seen this before).
'g'+'men'='gmen'
'set' going around 'gmen' is 'SEGMENT'.
(Other definitions for segment that I've seen before include "Part of citrus fruit" , "Division" , "split up" , "One of several parts of a whole" , "Part of, eg, an orange" .)
