Teleport Ground units only

I am pretty new to this but I am attempting to create a teleportation point.
The trigger is as so
[Any unit] [Enters] [Region 001]
Obviously, the problem is [Any unit]
But how can I limit this to only ground units?

Maybe add the condition

((Triggering unit) is Required: Ground; Excluded: Missile, Dead, Hidden for player (Owner of (Triggering unit))) == True

This use “Unit Filter Match”.

Hi Undead, Thanks it worked perfectly
