[Unsolved] Help with Spawn system

[Orion6D]

Hey guys, i'm having trouble with triggers. What i want is, spawn 2 units in a area/point (whatever) and when this units dies, the game wait 30 seconds and create another 2 units (same unit).

I can make units appear from 30 to 30 seconds, but what i want is: JUST APPEAR if the current units are dead. (If just one unit die, another can appear to replace)

Thank you!

Another problem appeared. The trigger is working, the problem is that it applies to ALL units on the map, without exception. And I don't want to relive my units when they die. Can someone help? I just want the player's units relive 15. (Hostile)

Add a condition to the trigger that compares the owner of the triggering unit with 15. In SC2 players are nothing more than integers (with the first human usually being value 1 with 0 being neutral).
