How do you unparent objects from one another in console?

[Deadlyfluffball]

Hello, this problem is driving me crazy.

Summary: I'm making a spaceship a parent (ent_setname bob) and making a bunch of combine soldiers the children (ent_fire !pickersetapent bob). Works great, but I don't know how to get them to leave their parent after I'm done flying them around.

So how do I detach these children from their parent?
