Destroy units

How do i make a trigger that destroys units when a specific player's unit dies..

I got the events and conditions down, I just cant find the right action to do it.

Unit Group - Pick All Units Owned by Player (Player 1) and Kill (Picked Unit)

Would be easier if you use pick all units owned by owner of dying unit.

He didn't say that the units he's killing are necessarily belonging to the same player as the dying unit, but if so, yes, that'd be better.

thanx, i guess i just didnt know what pick unit did.
