They take 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 not certain of the 'from the army' bit.
'they take money' is the wordplay.
I cannot quite see how this works, but
'take' could be 'r' (abbreviation for 'recipe', Latin for 'take') and 'r' is located in the answer.
'money' could be 'cash' (cash is a type of money) and 'cash' is located in the answer.
This explanation may well be incorrect...
(Other definitions for cashiers that I've seen before include "They handle money" , "They deal with money" , "sacks" , "Dismisses from army in disgrace, like bank clerks" .)
