Shelter soldiers from south capturing missile launcher (7)

Ross

I believe the answer is:

embower

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

'shelter' is the definition.
Although both the answer and definition are verbs in their base form, I cannot understand how they can define each other.

'soldiers from south capturing missile launcher' is the wordplay.
'soldiers' becomes 'REME' (Royal Electrical and Mechanical Engineers).
'from south' says the letters should be written backwards.
'capturing' means one lot of letters goes inside another.
'missile launcher' becomes 'bow' (I've seen this in another clue).
'reme' back-to-front is 'emer'.
'emer' placed around 'bow' is 'EMBOWER'.

Can you help me to learn more?

(Other definitions for embower that I've seen before include "Give shelter" , "Put in leafy recess" , "Surround, enclose" , "Introduce to the Hollies perhaps" .)
