An easy one for once.

I have a East Colonel named Kull...how can I send a message on-screen to the group that he is dead and they are to pull back to the pick-up zone.

you just need to make a trigger and put this in the condition field

!alive kull

and this in the on activation field

hint "the guys dead, pull back";
