Soldiers to call, giving advice (9)

I believe the answer is:

mentoring

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

'giving advice' is the definition.
The definition suggests a present participle verb which matches the answer.

'soldiers to call' is the wordplay.
'soldiers' becomes 'men' (men can mean a group of soldiers).
'call' becomes 'ring' (telephone call).
'men'+'to'+'ring'='MENTORING'

Can you help me to learn more?
