"Remove all units for player 2" trigger

What would be the action to remove all units for player 2 and player 3? Unit group - Pick doesn't seem to work, is there another way?

Unit group definitely should work.

Event
whatever you want to trigger the units being removed
Action
Unit group all units owned by Player2 and Kill Picked Unit

If that's not working, your event isn't being triggered.

yea... maybe you should point out what event you're gonna trigger it as well... the pick units action is good enough for it...

Nevermind, I went back and looked at it and I was using "Triggering unit" instead of "Picked Unit".
