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

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

'bears arms in the wars?' is the wordplay.
'bears arms' anagrams to 'EMBARRASS'.
But, I am not sure how this is indicated.

Can you help me to learn more?

(Other definitions for embarrass that I've seen before include "Make to feel awkward or ashamed" , "Disconcert" , "Make uncomfortable" , "Encumber" , "Cause (someone) to feel awkward" .)

I've seen this clue in The Sun.
