Handlers of money sacks from the army? (8)
I believe the answer is:
cashiers
'sacks from the army?' is the definition.
'cashiers' can be an answer for 'sacks' (I've seen this before). I'm unsure of the 'from the army?' bit.
'handlers of money' is the wordplay.
I cannot quite see how this works, but
'money' could be 'cash' (cash is a type of money) and 'cash' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for cashiers that I've seen before include "sacks" , "They handle money" , "Dismisses from army in disgrace, like bank clerks" , "They deal with money" .)
