Draw and turn gun on US military HQ (8)

Ross

I believe the answer is:

pentagon

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

'us military hq' is the definition.
(I've seen this before)

'draw and turn gun on' is the wordplay.
'draw' becomes 'pen' (I can't explain this - if you can you should believe this answer much more).
'and' is a charade indicator (letters next to each other).
'turn' is a reversal indicator.
'gun' becomes 'gat' (US informal term for a gun).
'gat' in reverse letter order is 'tag'.
'pen'+'tag'+'on'='PENTAGON'

Can you help me to learn more?

(Other definitions for pentagon that I've seen before include "Figure in plane" , "US building of high security" , "US government building" , "Five-sided shape" , "Headquarters of the US Defence Department" .)
