A soldiers last word? (4)

I believe the answer is:

amen

'last word?' is the definition.
(I've seen this before)

'a soldiers' is the wordplay.
'soldiers' becomes 'men' (I've seen this before**).
'a'+'men'='AMEN'

(Other definitions for amen that I've seen before include "Religiously 11 [THE LASTWORD]" , "Name for end to prayer" , "Extremist" , "So let it be" , "Name for prayer's end" .)

I've seen this clue in The Telegraph.
