Deliberately avoid military command (4)
I believe the answer is:
shun
I believe this is a double definition.
'deliberately avoid' is the first definition.
(I've seen this before)
'military command' is the second definition.
(shun is a common military parade command)
(Other definitions for shun that I've seen before include "Parade-ground language" , "Keep away from, have nothint to do with" , "Deliberately have no contact with" , "Avoid contact" , "military command" .)
