I believe the answer is:

come to harm

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

'suffer injuries as invaders' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'do?' is the wordplay.
I cannot really understand how this works, but
'do?' could be 'come' ('come' can be a synonym of 'do') and 'come' is found within the answer.
This explanation may well be incorrect...

Can you help me to learn more?
