Better money for army chiefs, maybe (3,5)
I believe the answer is:
top brass
'army chiefs maybe' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'better money' is the wordplay.
'better' becomes 'top' (top can mean to better or outdo).
'money' becomes 'brass' (brass can informally mean money).
'top'+'brass'='TOP-BRASS'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for top brass that I've seen before include "Important people" , "Leadership" , "Senior military personnel" , "Highest-ranking officials with best yellow alloy" , "Most important leaders, officers, etc" .)
