No closed range? Start shooting (4,4)
I believe the answer is:
open fire
This clue could be a double definition.
'no closed range?' is the first definition.
Although both the answer and definition are verbs in their base form, I can't see how one could define the other.
'start shooting' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for open fire that I've seen before include "where things may be hotting up" , "Order for military" , "army command" , "where you could be grilling" , "domestic hot spot" .)
