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

'soldier's' is the definition.
(I've seen this before)

'compel love?' is the wordplay.
'compel' becomes 'command' (synonyms).
'love?' becomes 'o' (love means zero in tennis).
'command'+'o'='COMMANDO'

'able to' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for commando that I've seen before include "Soldier trained for raiding" , "Soldier trained for carrying out raids" , "Green Beret" , "Soldier trained to carry out dangerous raids" , "going this way is unbriefed?" .)

I've seen this clue in the Evening Standard.
