I believe the answer is:

storm

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

'suddenly attack' is the definition.
'storm' can be an answer for 'attack' (storm can mean to take by force). I am not sure about the 'suddenly' bit.

'outpost or military enclosure' is the wordplay.
'STORM' is hidden within the letters.
But, I'm not sure how this is indicated.

Can you help me to learn more?

(Other definitions for storm that I've seen before include "Wind force 10 on Beaufort scale" , "Rampage" , "rage" , "Awful blow" , "X-Men character" .)
