Face attack (3)
I believe the answer is:
mug
This clue is a double definition.
'face' is the first definition.
(informal term for face)
'attack' is the second definition.
(to mug someone is to attack and rob them)
(Other definitions for mug that I've seen before include "person's face" , "Drinking vessel; dupe" , "attack" , "Drinking vessel for a chump" , "Drinking vessel for one easily deceived" .)
