Joining service again when lenient terms revised (2-10)

I believe the answer is:

re-enlistment

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

'joining service again' is the definition.
I can't judge whether this defines the answer.

'lenient terms revised' is the wordplay.
'revised' is an anagram indicator.
'lenient'+'terms'='lenientterms'
'lenientterms' anagrammed gives 'RE-ENLISTMENT'.

'when' acts as a link.

Can you help me to learn more?
