Weapons exploded, one in a pod (4,3)

I believe the answer is:

snow pea

'one in a pod' is the definition.
(snow peas grow in pods)

'weapons exploded' is the wordplay.
'exploded' is an anagram indicator.
'weapons' anagrammed gives 'SNOW PEA'.

(Other definitions for snow pea that I've seen before include "American plant" , "Mangetout (US)" , "pulse" .)
