I believe the answer is:

latrine

I'm a little stuck... Click here to teach me more about this clue!

'soldiers go?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.

'real nit shot' is the wordplay.
'shot' indicates an anagram.
'real'+'nit'='realnit'
'realnit' with letters rearranged gives 'LATRINE'.

'where' is the link.

Can you help me to learn more?

(Other definitions for latrine that I've seen before include "public toilet" , "office" , "Camp lavatory" , "An army loo" , "waste disposal unit" .)
