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

'guns of war' is the definition.
'weaponry' can be an answer for 'guns' (I have seen 'Big guns' mean 'weaponry' so perhaps 'guns' could also mean 'weaponry'). I'm unsure of the 'of war' bit.

'any power play' is the wordplay.
'play' indicates an anagram.
'any'+'power'='anypower'
'anypower' anagrammed gives 'WEAPONRY'.

'or' is the link.

Can you help me to learn more?

(Other definitions for weaponry that I've seen before include "fighting equipment" , "All one's arms" , "Arms in general" , "Arsenal" , "Arms; artillery" .)

I've seen this clue in the Sydney Morning Herald.
