Abandoned garage isn’t a place soldiers may gather (7,4)
I believe the answer is:
staging area
'place soldiers may gather' is the definition.
I can't judge whether this defines the answer.
'abandoned garage isn't a' is the wordplay.
'abandoned' indicates anagramming the letters (the original order is abandoned).
'garage'+'isnt'='garageisnt'
'garageisnt' anagrammed gives 'stagingare'.
'stagingare'+'a'='STAGING AREA'
Can you help me to learn more?
(Other definitions for staging area that I've seen before include "Stopping place en route to destination" , "place to break journey" , "Assembly point en route to a destination" , "place for getting men together" .)
