[Unsolved] Help with a thing

Please, i want help on one game, first:

I want a trigger, command, anything, that make the unit touch-kill, if it touch any enemy unit, kill it.

and second:

i want a way to one unit move like a boomerang, it goes at the targeted point
and comes to where it was early.

Touch kill? You mean, kill other units when it's in vicinity? There's a simpler solution: Permanent immolation. Just change it to an arbitrarily high amount of damage with the appropriate AoE. Change it to affect just the targets you need. Voila!

This would be the better solution. An obscenely high damage permanent immolation with no visual graphic.

lol and the boomerange thing i think will require some complicated physics systems which i doubt you can implement even if given to you

thank you all, the boomer i really dun need true, but one more thing, how i make a unit move randomly?
