Orderly in Ukraine attack (4)
I believe the answer is:
neat
'orderly' is the definition.
(I know that orderly can be written as neat)
'in ukraine attack' is the wordplay.
'in' indicates the answer is hidden within the clue.
'NEAT' is hidden within 'ukraine attack'.
(Other definitions for neat that I've seen before include "In good order, tidy" , "avoiding water?" , "Tidy - orderly" , "Tidy, well-ordered" , "Orderly, uncluttered" .)
