Dogs for my soldiers (6)
I believe the answer is:
corgis
'dogs' is the definition.
(corgi is a kind of dog)
'my soldiers' is the wordplay.
'my' becomes 'cor' (both are expressions of surprise).
'soldiers' becomes 'gis' (GI is an informal term for a US soldier).
'cor'+'gis'='CORGIS'
'for' is the link.
(Other definitions for corgis that I've seen before include "Welsh breeds of long-bodied short-legged dogs" , "Palace dogs" .)
