I'm trying to make a trigger kill a unit if that unit enters a location. The problem is that I can't find out how to choose a unit type and not a preplaced unit.

In Starcraft 1 it would look like: If current player brings at least 1 Terran marine to location kill -> kill all Terran marine for current player at location kill.

Event: Any unit enters region x
Condition: Comparison of unit-type of triggering unit and Terran Marine
Event: For each unit in (Unit Group: Units in Region Matching Condition(Comparison of unit-type of triggering unit and Terran Marine)), kill it.

Basically, this. You might need to create a local variable for the killing-portion, but I really don't want to write the entire trigger for you.

So you're saying that if we ever want a trigger to act upon a certain unit, we can never just specify that type of unit, we have to make a comparison?

You can specify the unit, but by comparing it. You compare the unit that enters the region to, in this case, a marine. If the unit if a marine the actions will fire.

Gosh, how I hate GE's logic -.-

It actually seems completly logical to me
Where's the problem? At some parts it's rather overcomplicated such as "brings 1 unit to location" is event "unit enters location" and condition "triggering unit == unitname". After some days (for me three days now) you'll understand it.

Ok, maybe I never fully grasped the concept, but for the life of me, I can't fucking figure out how to conditionalize:
"If any one of my pre-placed tree units is selected, and if it's in a certain region."

If someone would post a picture of a trigger showing this, I would be MOST grateful.

This is really annoying. I was so frustrated with this for at least a whole hour prior to making this post and on various other occasions, and then 5 minutes after posting, I figure it out. There seems to be a trend here... coincidence? I think not!

I suppose you can lock this topic.
