Show director mentioned gallantry award (5)

I believe the answer is:

emcee

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

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

I cannot understand how the rest of the clue works.

(Other definitions for emcee that I've seen before include "Someone presenting" , "present" , "Show host" , "Master of ceremonies (mainly US)" , "I announce" .)

I've seen this clue in The Sun.
