Armory (7)
I believe the answer is:
arsenal
'armory' is the definition.
(I know that armory can be written as arsenal)
This is the entire clue.
(Other definitions for arsenal that I've seen before include "Football club and military store" , "Weapon store - team" , "team effort" , "array of weapons" , "Where the guns are and who are The Gunners are" .)
