Back on coastal area shortly with new weapons (7)
I believe the answer is:
rearmed
'new weapons' is the definition.
(I've seen this before)
'back on coastal area shortly' is the wordplay.
I cannot quite see how this works, but
'back' could be 'rear' (something's rear is its back) and 'rear' is present in the answer.
The remaining letters 'med' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'with' acts as a link.
Can you help me to learn more?
(Other definitions for rearmed that I've seen before include "tooled up once more" , "new weapons" .)
