A marine journalist with weapons (5)

I believe the answer is:

armed

'with weapons' is the definition.
(I've seen this before)

'a marine journalist' is the wordplay.
'marine' becomes 'rm'.
'journalist' becomes 'ed' (short for editor).
'a'+'rm'+'ed'='ARMED'

(Other definitions for armed that I've seen before include "prepared to shoot?" , "with Browning?" , "ready to fight" , "brachiate?" , "Bearing weapons" .)

I've seen this clue in The Telegraph.
