Army medics checked out and took a stroll (7)
I believe the answer is:
moseyed
'took a stroll' is the definition.
(to mosey is to stroll around)
'army medics checked out' is the wordplay.
'army medics' becomes 'MOs'.
'checked out' becomes 'eyed' (to eye is to examine or check out).
'mos'+'eyed'='MOSEYED'
'and' is the link.
(Other definitions for moseyed that I've seen before include "Walked slowly" , "proceeded in leisurely fashion" .)
