Garment for chief of artillery (4,3)
I believe the answer is:
tank top
'garment' is the definition.
(I've seen this before)
'chief of artillery' is the wordplay.
I cannot really understand how this works, but
'chief' could be 'top' (synonyms) and 'top' is present in the answer.
The remaining letters 'tank' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for tank top that I've seen before include "Sleeveless garment" , "Item of gear" , "item of clothing to display biceps?" , "Upper body garment" , "Sleeveless pullover" .)
