Sloe gin is ordered for lots of soldiers (7)

I believe the answer is:

legions

I'm a little stuck... Click here to teach me more about this clue!

'lots of soldiers' is the definition.
The definition and answer can be both groups as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'sloe gin is ordered' is the wordplay.
'is ordered' is an anagram indicator.
'sloe'+'gin'='sloegin'
'sloegin' is an anagram of 'LEGIONS'.

'for' is the link.

Can you help me to learn more?
