Show support for military facility (7)
I believe the answer is:
airbase
'military facility' is the definition.
I know nothing about this answer so I can't tell whether this works.
'show support' is the wordplay.
'show' becomes 'air' (both can mean broadcast).
'support' becomes 'base' (base is a kind of support).
'air'+'base'='AIRBASE'
'for' is the link.
Can you help me to learn more?
(Other definitions for airbase that I've seen before include "Where one may see fighter pilots" , "Hurricanes may come from this" , "military use it" , "hardly a no-fly zone" , "military unit" .)
